Non Existent Customer Service

Oh my word!! I have never had such a poor experience. I have an FNB Credit Card and I made a payment into it on Friday. Called today to ask them to transfer the payment into my budget facility so that I can pay it off. Firstly, I had to dial 3 different numbers and then was put through to no less than FIVE different people before someone could "assist". Then, I'm told that they can't help me as I don't have the FNB app so they have no means to verify me. The reason I don't have their app is because in order to get the app up and running, I have to go into a branch. SO .... I now sit with a big fat credit on my card and can't pay off the budget facility, unless I go into a branch ....... Thank goodness I don't have any other accounts with them and after this, I never will. Their customer service is awful!
