@tk1900 - As I said I always provided the proof. I asked before what I needed to provide and I sent them what they asked for, they even confirmed to me in writing that it was sufficient. They stated (again, in writing) that as long as the money comes from the same account, I only need to provide proof the first time. Even if this wasn't the case I would still have been able to provide proof each and every time. But the last time they just didn't even give me an option to provide proof but just closed my account.
