My experience with this site was positive, up until they banned my friends from the site. They were going against the rules and had other accounts, which was obvious as to why they were suspended. But when I helped out a friend by buying him an item he wanted, they banned me too! I sent them a nice email, asking why it had happened, and asking for them to fix the problem. They flat out refused, and accused me of having multiple accounts too. They also took about 2 weeks to even respond, with the response that I would not get my account back because they assumed I was my friend.
When I showed them proof I wasn't my friend, they said it wasn't a real account and that I was lying and they can't help me. I loved the site up until they pulled this crap. The customer service team was not helpful, and while I do understand they must be busy, they certainly should look into their fake account claims more carefully.
All in all, the site was great when they actually let me be a part of it. If they'd fix my problem and actually listen to me, I'd gladly write them a bit of a better idea, but unfortunately they don't want to do anything for their customers.
