Kwantum Reviews 

They never removed the leftovers from the carpet fitment and refused to do so.

When we enquired why they said they do not do this and told us so.

At no time were we ever informed that they do not remove their mess after a job.

Neither in writing or verbally i.e we were never given any indication of their terms of fitment.

Not what we would expect from an organization of their perceived calibre.

Shame on you Kwantum

You need to learn from your competitors on how to treat a customer

We bought customized curtains from Kwantun-Zaandam. They have very good collection & salesperson was very helpful. They guided us very well manner & provided all information. I will definitely recommend buying things here.

Limited stock, great service.

I thought Kwantum could not be worse at customer service but I was so wrong. There is no such thing as customer service at Kwantum. After placing my order for a simple kitchen mat of 2mx1m on 11/03/22, a day at home waiting for delivery that never came in May. Six trips to the store, several emails to ask whereabouts of mat and my in person attempts for someone to tell me when to expect the mat, 3 in-person promises to phone me with an update that never came, hearing their lie that they called when they did not (several times). Note the reply to my last review whereby I was 'schooled' that custom orders can not be refunded and no mention of where my mat is or when to expect it. Zero email updates to me along the way. I still never received an explanation for all the time wasted to get the kitchen mat. Yesterday they refunded me.

Worst store ever - DO NOT BUY HERE.

I have no words to describe the nightmare experience I am having with this store. I order custom made curtains in the store in de Pijp - after more than a month receiving no emails and calling the store once in a while to check on my order (even went there 2x) I got an email saying your order was delivered to the neighbor a month ago. WHAT?
I mean I had been talking with an employee 3 days before and no one told me this. Now the neighbor (not even the same building - unbelievable) says he doesn't have it and apparently it's nobody's responsibility.

I have been calling the customer service almost every day for the past MONTH! I don't have curtains or my money and every time I call they end up saying I am right and will process a new order (just wait for our confirmation email) just so that another person tells me the next day IT'S NOT POSSIBLE.

I am desperate. Asked to make a formal complaint - not possible. Asked to have my money back - not possible. Asked for my curtains - not possible. Don't know what to do anymore.

Reading the other comments here I see this is not an isolated case. THIS STORE IS A SCAM. BE AWARE

worst customer experience ever. Stayed at home 3 times and no one showed up. Calling customer service takes 45 minutes every time. Still no solution.

Update 13-6-2022. Replying on their feedback through social media seems to work a bit. Early May we sent an "ingebrekestelling" as well, with 14 days notice. Today I got a response that they do no want to show up at all. We bought and paid curtains in January but even in June we still do not have the curtains and now they said they do not want to hang them up anyway. Proposed compensation was a laugh, we made a counter offer but are preparing legal steps to get this issue solved. This company does not deserve a department that is called "customer service". Never been treated this way as a customer.

Update 13-1-2023 After 51 weeks, we have our curtains! However, we had to find a special solution for this case. Kwantum offered a small refund and a refund for the assembly. Curious to know how long this will take, but at least we have the curtains now.

Installation service and response to emails should be handled better.

I am very disappointed with Kwantum. I will never use them again. We paid for a new floor to be installed and fitted. We cleared our house of all furniture, we removed old floors and today the fitter didn't show up. Kwantum told us my wife had canceled the appointment and to take it up wth her. Why do they lie ? All we hear is they cant call the fitter, they dont know when a next appointment will happen. The system updates over night, they can call us tomorrow. It is a constant set of lies and delays. Kwantum you took our money and messed up our house and now you cant tell us when your coming to fit the floor. Useless, we will never use or buy from you again.

I did shopping in quantum 2 weeks a go I found the staff very cooperative. And I saw very nice stuff there I m happy with quality as well

Good service, my order was carried out efficiently. The choice of the store was also determined by the good price of the product that I was looking for on the market.

WE ARE VERY SATISFIED AND HAPPY WITH KWANTUM'S plissegordijnen.

Good quality for reasonable prices. I am happy with my ceiling lamp.

Shopping at Kwantum based in the Netherlands is generally not recommended. There are no guarantees bought items will arrive. Customer service is non existent and generally items of low quality. there are many shoppers who have been scammed on the internet. I recommend praxis.

I bought 2 floor matst from them in 2 different colors. Only 1 arrived, in a different color than the label said it should be so I don't know if the label is wrong. But if the label is right the item definitely isn't the same shade of grey as on the website since it's more off-white. I mailed them on friday, didn't got a reply so far, so I called them. 20 minutes later, still didn't spoke to anybody. I called the most local Kwantum shop and the woman tried to help me, but the only reply she got was "We are busy, we will mail back but we don't know when". I needed the mats urgent because I use them in a project, so I am really pissed off about the way this is being handled. I could go get one from the shop now that it opened again (lockdown), but then I have to pay again and still wait for a mail back from costumer service to get my money back.
