Unprofessional and useless

On 29 April my husband settled the loan amount in full and the amount was R17124.32. FNB could not locate the bank so we paid it into tymebank credit card account, but until today no one can acknowledge the payment. Numerous emails and calls to tymebank is fruitless and frustrating as a debit will takes place in 5 June and they're unprofessional and useless. A few calls from their branch over a week ago and empty promises and we are still at the same point of the payment not being confirmed. We have sent the proof of payment over and over and over again and had to pay a fee at FNB for a proof of transaction for ONLY the month of April. That was also emailed to them but I wants to warn clients to be careful and consider before dealing with this bank. I want this matter resolve today
