Poor service delivery and unkept promises

FNB connect debited more than they were supposed to do so. I had downgraded on time, and I was promised that the right amount would be debited but to my misfortune, the promise was not lived up to. R256 was debited (for 5gig) but I only got 2gig. They said to rectify the matter they would not debit for the next three months, but yet again, they could not keep their promise and R95 was debited from my account. I am absolutely appalled by the department’s business etiquette.
