Missing Payment

I'm utterly disappointed by the service that Nedbank is offering of late, especially with regard to the Customer Care Department. It's like those people are programmed or they are not allowed to use their minds when dealing clients. I have a payment that was credited to my credit card in February, no matter how hard one tries to explain that the account is in arrears, they still insist on you committing yourself on when a payment will be made. Nobody thinks that maybe the client is telling the truth. Even worse, they send you a SMS as a reminder with a contact number that does not receive incoming calls. How the hell should respond to the SMS. *** is the number provided. This is very stupid, How does a payment goes missing if I'm using one method of payment every month. until today, that payment has not yet been credited to my account.
