Stopped Bank account

Standard bank stopped my account Thursday 31 July,l over a R390 deposit I made from my Capitec personal account to My standard bank account, I haven’t been able to pay for my car, my insurances, my kids school fees the list is endless. I have sent proof of Payment for the funds I have been sent from pillar to post since Friday 1 August everyone I talk to is telling me a different story sending me back to Capitec and Capitec has been telling me there are no Alerts on their side my account is clean. I am very angry and disgusted, why am I being made to verify R390 funds when I have way above that on my account that I need to used. It’s only been 2months with the account where did they get the idea of transactions that go on in my account this soon. It was the month end transactions are expected to be made. I don’t have any reference number I don’t have any case number at this point I need legal help cause this is beyond my patience.
