Horrible horrible service to Premier Private Client

I have been an FNB client for over 10 years and I am disgusted with the decline in the quality of service over the years. I app**** for a limit increase on my credit card and was given a new card but the limit increase app**** to the old card. Now I have two credit cards linked to my profile which doesn’t make any sense and on top of that the new card doesn’t work. In addition I am getting daily calls on a daily basis that I am owing, how is that even possible when I have a positive balance on my card. I’ve been on the phone with them on a daily basis and it seems nobody knows what to do. They don’t even have a clue on how to fix an issue that they caused!! I am so disappointed in FNB you are really failing your clients. If this is the treatment you give your “ premier private clients” then I would rather move to another bank then be harassed daily for something that your fault.
