Poor Service

Have had nothing but a bad experience from African Bank. First of all I have been paying month to month and they refused to update my ITC and now I have settled my account on the 16th of March and they are still deducting my money. I was told to send proof of payment when I called yesterday of which I sent before. Yesterday I was told to wait 24 hours, now 24hrs is finished am told to wait 48hrs...this is madness. I cannot even reverse their debit order because they have put some mandate on it. The lady from African Bank says they can't refund me until settlement is processed...what an inconvenience..this is real madness and am just not happy and will never use their services again.
