I am very disappointed with the service…

I am very disappointed with the service I have received from Mozillion over the last few weeks.

I spoke to several customer service agents regarding my account and at no point was I clearly informed that my bill needed to be paid by card. Different agents gave inconsistent information, which caused unnecessary confusion, stress, and inconvenience.

Had the correct information been provided from the start, this issue could have been resolved quickly and avoided altogether. Instead, I spent a significant amount of time trying to get clear answers, only to receive conflicting advice from multiple representatives.

Customer service should be accurate, consistent, and helpful, but unfortunately that was not my experience. I hope Mozillion reviews its staff training and communication processes to prevent other customers going through the same situation.

I am now awaiting a proper response to my formal complaint and an explanation as to why I was not informed correctly in the first place.

Hi

Thanks for getting in touch, and please accept our apologies for the confusion.

This email was sent in error and caused when we migrated your account from our old platform to our new Version 2 platform last May. During that move, your SIM plan end date was set incorrectly by mistake.

We have now corrected this and your plan date is set to the correct date. There's nothing you need to do on your end until then.

If you have any further questions, just let us know and we'll be happy to help.

Kind regards

Money Saving Expert recommended you for great phone deals…

I noticed that Money Saving Expert were recommending your company for a brilliant deal on purchasing a new mobile phone. Investigating the offer further I was amazed at the bargain price I was paying when most other sellers had significantly higher prices. The ordering service was great and delivery was 2-4 working days - it was delivered by DHL in 2 working days. Very pleased with the purchase.

Unbelievable deal

Got a new phone and a really good plan for £30 cheaper than the mainstream providers. Ported my old number across without any issues. The whole experience was completely seamless and have recommended to everyone.
