this happened to me today too. I was buying 10m via money bookers, and after 2 mins of me paying, I got suspended. However they said that it was their mistake, they were giving me a 5 dollar coupon, and refunding me the 7.50 I paid for the 10m but never got because I had been suspended.
I got banned once because they thought I had charged back like $100 of RSGP payments when I hadn't. They continuously called my phone, and each time I told them it wasn't me they said it was and refused to unsuspend me, but they kept calling anyway. I don't know, Playerauctions needs to get their shit straight.
