FNB Covid Loan

I am very disgusted with FNB. I am great full that they were able to help a lot of people with their covid loan, but as a big bank/company like this, you would think they have all matters under control. But for me this is not the case. FNB made a mistake of putting more funds into the covid loan than as the agreed contract, and since then has not restructured this amount and all of a sudden I am obligated to pay an amount that is way more than the original amount as per the agreement signed with FNB. I has phoned and emailed so many times and still nothing has been done. The last time i phoned in was on the 20th of October - an escalation was apparently sent to to do the restructuring and change the debit order date and yet still no one has been in contact with me nor has it been fixed. I need someone, anyone to just fix this error that fnb made immediately, as i will not pay more than was agreed upon with an binding contract!!If this is the way that fnb wants to do business by trying to get more money out of a client, i am more than happy to change banks.
