Aggressive bank system

Standard Bank vehicle account has a poor service to the client . I have been on a manuel payment for about a 8months now using the same reference number never missed a payment. Now for the month of May the payment was made on the same due date with the same information as the previous payment. 3 days later I received a message of from them that the account is in arrears , Immediately call the them and the consulted request a proof of payment which I did shared on the spot . Five days later I received an email from the attorneys that they are now handling my account due to the arrears and I must make a payment arrangement with them .

On my second attempt to consult the bank I was been told that the money is not reflecting on their system meanwhile I’m using same bank . I request the proof from the consultant from their system on the spot but I was told that the only thing they can be provide is the account statement which is not available immediately. And advised to send an email to *** so the bank can allocated the payment.
