Shocking lack of customer service.

I have been a customer of FNB for over 10 years and have found that their service of late has been extremely disappointing. I app**** for a change from my cheque account to a fusion account in December 2019 upon the advice of one of their consultants. Since then, I have not been able to receive the correct contract for me to sign and accept the T&C's. I have been in receipt of contracts that have the incorrect dates and tax implications (these read as if it is referring to foreigners tax implications while I am South African). I have spoken to many consultants over many months and each one passes the buck and still cannot rectify my contract. I have now been ignored since March, with zero communication from anyone at FNB. Even when I use their online complaints portal, I get an automated or generic response telling me that someone will be in touch but then, nothing! This has started to affect other products that I want or need wrt my finances as this contract looks like it's outstanding or incomplete from my side, on their system. Beyond frustrated and disappointed. Perhaps they grew too quickly in their customer base that they no longer have the resources/s****s to assist their customers anymore.
