Cheats and ****s

After settling my personal loan account with with FNB, a week later the the bank tried to debit me again. I contacted them through the chat and the agent confirmed to me that the account was upto date and paid in full. They now say it is not. FNB who I have banked with through business aa well, has deteriorated into the depths of hell. They are rotten to the core and are narssistic cheats.
