FNB, How can we frustrate you!

So I was recently convinced by an FNB consultant to upgrade my Gold account to Premium. I have a credit card and was checking the balance I owe on the credit card. The figure I saw did not make sense to me because the balance I owe and the credit left on the card does not add up to the maximum credit on the credit account. I decided to visit a branch to get clarity and went to Davenport FNB, where I was met by Leisha on the front door, very rude and unhelpful I must say. She told me that I had to contact the call center and literally refused me entry into the bank to speak to a consultant because they could not help and the call center is my only option for this.kind of query. I called the call center and I am still on the line, holding for the consultant while I type this. Its been 55 minutes (I have a pic of the call duration as well if you dont believe this) I still do not have an answer why my account is the way it is. Really frustrated by FNB because they have wasted my time, now airtime and I have been with the bank for a very long time. After this ,I am going to use my time wisely by looking for a bank that actually helps and switch.
