Bad service

I tried to make an online purchase to a trading platform and was blocked by Standard Bank and the reason is that they are under the assumption that I'm going against some laws regarding betting. I'm trying to deposit into a trading account in order to trade and don't understand why the assumption. It's not the first time I do this and now it seems as if I'm trying to commit ***** because that is the department it was sent to to block me. Should I rather close my account with standard bank and move to another bank?
