Prior to going in store at 4010, I did some research and had a particular sim brand in mind to…read morepurchase. When I arrived at 4010 asking the staff about sim card, they recommended brands from large telecommunication companies in Germnay, but when I wanted to purchase a particular brand of sim card which was not from one of large communication companies the staffs attitude changed. They weren't really interest in any queries I had to ask about that product and was very unhelpful and also turn unfriendly (maybe they don't get much commission from that brand). I still purchased the sim card, but had a hard time activating it because was in German, I went back to ask for help, but no help at all, not interested one bit. What is even more sad is their website for staff profiles (also includes the people who served me) claims to be helpful customer service with patience. Is anything but that, a store that is about glitz and show, but no substance.
