CHARGING ME FOR A SERVICE THAT WAS NEVER RENDERED AND CANCELLED

I CANCELED THE INSTALLMENT WITH VUMATEL AND WEBAFRICA AND I CONFIRMED THIS TELEPHONICALLY AND VIA EMAIL

THE ROUTER WAS DELIVERED TO THE WRONG ADDRESS

WHY AM I GETTING CHARGES TO MY BANK BECAUSE YOU TRYING TO CHARGE ME FOR A SERVICE THAT WAS NEVER RENDERED AND CANCELLED!!!!

I HAVE RECIEVED CHARGES FOR A failed debit order OF R50 administration fee, FOR SERVICES NOT RENDERED????
