MTN IS INCONSISTENT & DISLOYAL... WILL BE CANCELLING MY CONTRACT SOOOOONNNN

MTN has the worst customer service, their instore consultant and their call center consultant have no idea of what advise to give to their consumers. I have asked MTN if its possible to move my payment to the 10th of every month the instore consultant advised that it is possible and assisted me with that. Today both my lines are suspended i called MTN today and i am not that my payment can not be moved unless its a debit order and i do not want to change my payment method to a debit order because i do not want to find myself in a position of being double or triple debited like other MTN consumers who still find their lines suspended after being double debited. When this contract ends MTN will definitely miss my loyalty, because clearly they are inconsistent and disloyal to their consumers
