Sold me a used phone claiming it was a brand new one! When I received it the box was sealed. However, when opened, there were small scratches and dents on the phone. When called Samsung, they confirmed that the phone was already activated more than a month ago! The shop has sold me the phone under the false claim that it was brand new! Be aware! They are liars! They will tell you that the box is perfectly sealed and nobody ever opened the phone before. They very skillfully put a seal on, from outside it looks like it was not opened. But like I said, the phone was already used inside the sealed box! I cannot believe the Carrefour allowed them to sell their phones on their website. This is how I bought it. And it is listed as new! This company are liars and cheats and they are acting illegally by selling a used phone and claiming it is brand new! I will be taking action against them. But consumers, be careful, stay away from these cheats!
