Poor query resolution

Good day

I have experienced errors trying to transfer money into my credit card account via both the fnb app and the desktop site for close to a week now and keep getting errors such as this transaction is not authorised. I called the FNB callcentre ands spent close to thirty minutes speaking to everyone from the credit card department and even the ***** department for assistance but have received no joy.

I also logged a complaint via the FNB online system and am yet to receive any feedback. In the mean time the credit card interest in increasing. I am really dissapointed with FNB as this does not seem a complicated query to resolve.
