FNB Account "Upgrade" and Overdraft Unwanted - Untrained and Irresponsible Bank Teller

I've tried to get information from FNB secure chat and by phoning and emailing - none answered my questions, or rep**** to resolve my issue, so I am forced to complain here. My FNB Gold car expires next week, so yesterday I was forced to find a lift into the nearest branch which is Herm**** - 85 kilometers away. I was under the impression that my card would be issued immediately at no cost to me - that is what the FNB app messages I received telling me to renew my card said. Ordinarily, I do everything in my power to avoid going into an FNB branch - it is almost always a long and unpleasant ordeal. I should have known the teller was grifting me when she went on trying to sell me FNB life insurance, despite me having no legal dependents, spouse or assets. I don't even earn enough monthly to be in a tax bracket. The teller told me that I qualify for an "upgraded" account to Aspire, and that I would earn eBucks. She said absolutely nothing else about it. Then, instead of just giving me my card, told me I would have to make the arduous mission back for another 170 kilometer round trip next week to collect my card. I told her that the FNB app messages said I could have my card same day and she told me that was a lie. After leaving the bank, I noticed an extra R1000 in my current account. I had no idea what that was about. A friend of mine who is a customer of Capitec explained that the FNB teller had probably given me an overdraft, but that it should not reflect as my 'cash credit'. Last night, I moved my current funds into my FNB savings pocket, as I do every day applicable. Then suddenly panicked because it occurred to me that I could be charged for doing that if the extra R1000 was overdraft money. I tried to get help from somebody on the Secure Chat and got no information whatsoever, except for to say that I would be charged but they had no idea what the interest rate is, or anything else at all, then abandoned my query before it was satisfied. This morning, I received an email demanding a lot of documentation I simply do not have - I am on an indigent income. Kindly cancel this overdraft immediately and take your money back, FNB, before you land me in trouble I cannot afford. Return my account to the Gold account I have been happily using for years to date - I want nothing to do with the Aspire account that that untrained and financially irresponsible FNB Herm**** teller flogged me without conscience to properly inform me of any of the added costs and inconvenience. I will make the tremendous effort to arrange a lift and cancel all other engagements to collect my usual Gold card next week from the Herm**** branch and hopefully never have to step inside an FNB branch again for another five years (or however long the card is usually valid for). Thank you.
