HOW CAN WE HELP FNB

So for the first time in my over 30 years of working, my debit orders bounced. Through no fault of my own, neither that of the bank's. I have had an overdraft virtually all my adult life. I managed to get the funds together within a couple of days, I received a call a couple of days after the bounced debit orders, saying that my overdraft would be taken away, I asked the lady not to do that as I had requested service providers to put through debits again and if she withdrew my overdraft it would all bounce again, She said she had no choice. I managed to get back on tract financially all within the same month. I have to laugh to myself every time I see an FNB advert, really - HOW CAN WE HELP YOU. I went to my local branch, spoke to the manager, she herself found it highly unacceptable, given my history and the amount of days in which this all took place. She didn't do anything about it though. I have had several calls since, offering me my R17500 overdraft back, I have had several calls offering me a credit card. I have declined on both. Yesterday I needed to open an 'ESTATE' account. The lady again offered me a credit card, which I declined. My proof of residence was 3 months and 5 days old. I was told it was not good enough and that the account could not be opened until I had a proof of residence not older than 3 months. I used that same proof of residence at SARS without any problems. I do still have a FNB account, which I will be closing as soon as I have moved all my debit orders over to another bank. So FNB - HOW CAN YOU HELP ME. Don't bother, I don't want or need your help
