MTN ****

My father took a phone on contract, for 2 months he has not been receiving his airtime. At first they said it was allocated 27th of April and he ignored and thought he will check the following month but still nothing in May and on email they said it was allocated on the 27th so when he asked if heis not sharing the number as it was “recycled” and still getting calls for the other person over a year later they then said he owes payment for May. He sent a screenshot of the payment from the app on the 13 June and still nothing, then again on the 18th followed up if they have received payment but still no response from MTN. For 2 months the airtime he is paying for has not been allocated even after asking them to check if there have been calls made from the number in the past 2 months, they are quiet.
