Unfortunately, I don't have any further information about this. OP self-excluded with GameStop, he needs to speak to them why they gave him wrong information about which operators supported their services at the time. They do have live chat and e-mail support 7 days a week.
@beb067 this case is from before we supported GameStop.
So did your customer service surely? Why didn't they tell him (or Richy) you weren't working with Gamstop, rather than telling him you would refund his deposits?
I still don't understand why you discussed this case with Gamstop if you had no working relationship with them at the time, nor how it isn't a breach of the DPA to do so?
Also, if Gamstop weren't in any agreement or relationship with you at that point in time, why exactly are they allowed to tell you not to refund after your decision had already been made? That makes no sense at all to me.
