FNB - Customer Service - What Customer Service????

I have a Revolving Credit Facility with FNB for which they deduct the payment from my account on a monthly basis. In the middle of February 2021, I tried to access my Revolving Credit Facility only to find that I could not, as such I contacted FNB to find out what is happening. I have been pushed from pillar to post as the number I'm given on my FNB Banking App is incorrect and spent hundreds of Rands phoning every week (in the beginning) trying to get this issue resolved. Every time I finally get put through to the correct department I am informed that the consultant cannot assist me they need to refer the matter to their Team Leader and the Team Leader will contact me. I have even requested to be transferred to the Team Leader which cannot be done as the consultants are working from home, so I have requested a contact number for the Team Leader as I know I will not receive a call only to be told they do not have a number for the Team Leader they email the Team Leader. I have gone so far as to ask for the email address only to be told they are not allowed to give it out. To date I have not received a single call. I have even made use of their Secure Chat facility only to be told my account is in arrears, which it is not as FNB takes their money before my money it even hits my account. We as FNB clients are charged a small fortune every month in service fees, but when there is a problem there is no service forthcoming, what am I paying for???? Does it really take 2 months to resolve an issue??? I am now at my wits end and will be looking for another bank.
