Breach of Contract

On 28 May 2018 I upgraded my contract with MTN. The Advertised tariff was R 369 per month for a Nokia 7 on the MTN Made for Me M contract with deal code ********** CT94.

For June I received the allocation for my old tariff plan (My MTNChoice 25mins) but was billed for the new tariff plan. I contacted MTN customer care and logged a support ticket. The representative informed me that he would escalate to the Billing department. A few days later I received a SMS informing me that the issue was resolved. However there was no change to my allocation and I did not receive any refund. For July I again received the incorrect allocation. I once again contacted MTN with a similar result, the customer support agent referred to billing department and a few days later I received a SMS notifying me that the issue should be resolved. However nothing has changed. I am currently being billed for a tariff but not receiving the correct allocation and due to this I am also being billed for additional usage that should have fallen under the included allocation of the Contact plan that I signed for.
