Standard Bank ***** Dept service is appalling

Standard Bank ***** Dept is the worst... I had someone transfer money from their Standard Bank account to my Tymebank account, and they decided it would be a good idea to block my account. Getting my account unblocked is proving to be a nightmare... From being told it'd take 7 days for the matter to be resolved, to now being informed it takes 4-6 weeks .. and then being told we need more affidavits and letters from banks and ****. And upon calling them for a third time, now it's apparently going to take 1-2 days to be resolved. What the hell is happening in the ***** Dept. And what right does Standard Bank have to block my account, even though I don't bank with them. Their service is appalling to say the least.
