Account blocked

My savings account has been blocked when I inquired about it I was told that my account had recieved a payment from a *****ulent account that was reported they then asked the forensics to provide a detailed explanation . I then got a response that I recieved R3000 from a push payment **** yet I got the money from my parent and I've received way more from the same account but never got blocked and the sender's account is not even blocked very weird. I hope this gets solved soon I can't even solve it over the phone that time I don't time for going to the branch .The bank is the ghetto if it wasn't for the investment I have I would have closed this bank long ago
