Disgusting service and day light *******

recently settled a loan with African Bank, under a year old close to 60k . i settled in October and was charged finance fees in November of R500.00 some odd. i was initially disputed it and then agreed to pay it, the consultant confirmed my account would be debited and it wasnt. i followed up in again at the end of November only to be advised my bill is now R900.00 as African bank did not debit. i disputed again and logged a formal complaint under ref : ‪***‬. i followed up again and they advised that still working on it ....2months later all that is happening is that my bill is being increased with fees on a settled accounts. Whenever i call , they advise i cannot be directed to complaints or anyone senior . I'm so disappointed as it was a large settlement . African Bank is really unfair , i really do not think i should be liable for any fees , esp that its a fault on their end .
