Pathetic client service

I app**** for an increase in credit card limit. I received a quotation to sign and send back via email. I received the quotation on the 15th of January and emailed the signed copy on the 18th of January. Subsequently I received absolutely NO response or feedback from FNB. I made several queries on secure chat using my app only to be told to call card division. The 6th person I chatted to was Yonela from secure chat who told me it was approved and funds take 5 to 7 days to load. I thereafter made more queries all telling me the same thing. However funds was not loaded onto my card. I have the screenshot of each conversation and with whom. I called credit card division 8 times who told me the matter was escalated and that my case was completed on the 7th of Feb and was successful. I called on the 28th of Feb only to be told that my quotation had expired and I need to start the process again. I am extremely frustrated and angry at how FNB treats their clients as I needed the funds to pay for a medical procedure. Each time FNB did not get back to me and I was the one that had to make over 15 requests. Today, the 1st of March I receive an email from FNB stating I should use the iContract service and they sent me a reference number but guess what, it does not allow me access even with entering the reference number so I called card division again and was told sorry due to technical error it did not work and instead I will receive an email with the quotation to start the process again. This is extremely annoying as FNB will NOT admit their mistakes. And not once was apologetic for giving me the run around and pushing me from pillar to post. Pathetic service and seriously considering switching my bank.
