Worst bank EVER

I use TymeBank to trade but can't because someone is running a **** by advertising appliances cheaply and ask for a delivery fee of R300 or R350 upfront but then give them my TymeBank account details to make the deposit for the delivery fee. Then the ******** block that "customer" on WhatsApp and tell me that a friend is going to pay R300/R350 into my TymeBank account. I then deliver services to the ******** to the value of the deposit. The "customer" then complains with TymeBank that they have been scanned and TymeBank blocks my account. So I'm being pulled into a **** of which I know nothing of. Why doesn't TymeBank interview me to get the real facts but rather take a stranger's word to punish me? I have done nothing wrong because I receive funds, deliver services and that's it. Now TymeBank expects me to do a refund to the "customer" and I sit out of pocket after I delivered services to the ******** and I sit with a blocked account and can't trade with my TymeBank account. It's very unfair of TymeBank to treat me like this. When I phone them then my case is always under investigation and then I get sms's saying that my case has been resolved bu it's not. When I phone again then they are extremely rude and puts the phone down in my ear when I insist on speaking to a manager or supervisor. They never call back when they say they will. It's the worst and slowest and rudest bank ever. I have to have this account because my clients are TymeBank clients otherwise I would have left them long ago.
