Not great, ignoring issues for years, but not entirely terrible
I am a long term customer (3+ years, weekly orders) and Rohlik.cz are fairly good.
Polite communication, but too often not able to help (I'll go into that in detail later). I had mostly good experience with couriers. Only negative about them is, that some of them don't have change back when paying in cash and instead of them going to a shop hundred meters away they are expecting me to find small coins in my flat (going up few levels, finding spare change and going down while they wait).
Their prices are not great, but not that bad either. I think it's still worth the saved time and the convenience.
As a company, they are rather frigid, ignoring long standing issues in their process. For example, if you place a morning order and they don't have the items even though they were marked as in stock (their fault), you cannot communicate with them what alternative item you want. Only SMS arrives, informing you you aren't getting some item and that they don't want to wake you up. It's infuriating when you are already awake (sometimes for hours) and you cannot message them back (the number doesn't accept SMS or calls), call them back (customer support doesn't work that early) nor write an email (it's handled too slowly, after the packaging is done, so they just respond that they can't change it). I tried all these methods and none lead to being able to pick alternatives. This problem is present for literally years (at least 3). I wrote them several times, even wrote a blog post about the issue and an analysis of several possible options how to fix this.
Their web app could use some improvements. For example items you place in your basket should be "yours", reserved for you until you finished your order or some time passes (e.g. an hour or two). It's quite common that you think you are done and then just before finishing the order you are informed that the items you have in your basket were "stolen" (when going with the real life shop parallel) from your basket by some other customer. Same reservation should be done for delivery times - when starting picking items, you select a delivery slot and that slot is reserved to you until you finish the order or too much time passes (again, an hour or two should be enough).
They also don't seem to value much loyal nor premium customers. Last case demonstrating this was, when they posted that at 10am next day they will be allocating delivery slots for loyal/premium customers. So I waited a day before ordering, thinking I could get a good slot. They lied. No extra slots were available following day at that specific time, so I have to wait longer than if I would have waited if I have had ordered the day before. I wrote them an email if they could move my delivery slot to earlier date and time. It's now over a full work day and still no response, not impressed with their speed and honestly I am not really expecting they will help me.
