Well, finally got a reply from their deposit/withdrawal person today. Apparently in order to keep their deposit methods as private as possible, they're now allowing people only one deposit method other than the WU, MG and Gold-Pay options which are available to every customer. In addition, once you abandon a deposit method, you're no longer allowed to change back to it. Currently I'm on eWalletXpress, were I to want to use their VISA processor now I would have to abjure EWalletXpress for good (not a problem really since their fees are outrageous).
I was somewhat disappointed by their response, honestly. I've played at 5Dimes for literally four years now, and only in the last six months have I been winning enough to request a couple modest (<$1k) payouts. I thought they would take my money however it was convenient for me. I'll probably just quit that shop altogether, I've enjoyed it a lot as a rec. gambler, but I'm sure I'm about to get limited soon anyway. Such a shame too, I loved being able to bet on college hockey.
