Pathetic Service

Have an MTN contract I get SMS's threatening to discontinue my service due to non payment. I have made all payments due to MTN, I have all the proof of payments.

This happens weekly I phone them and have to speak to some *********** call center agent who cannot understand that all payments have been made. They admit every time I speak to them that the fault is on their side as they can see the payments on their system and assure me my service will not be suspended. BUT BELOW AND BEHOLD GIVE IT A COUPLE OF DAYS AND THE SAME HAPPENS AGAIN.
