FNB Conduct Disgraceful

I am in restaurant business catering mainly for local and foreign tourists. I have an unblemished record with a number of FNB accounts for 25 years. That was until COVID struck. Since COVID I have requested assistance from FNB on numerous occasions to help keep business open. They rejected my requests with "we lost your application in system" or "we don't have any funds left" Not only that but they are now penalising me by forcing me to reduce my overdraft by R5k a month. When I queried the reason for this I was told that my current turnover after opening after lockdown does not justify the current overdraft facility. I told them that's a ridiculous reason because my turnover has dropped dramatically due to lockdown. It's out of my control!! Its a disgrace that FNB can treat it's clients without any empathy or understanding!! All FNB is interested in is their own interests. Their slogan "Whay can we do for you" is a blatant lie!! It's not surprising that they were the bank with by far the most complaints in South Africa. I wonder how many other businesses are out there that have been treated the same way?
