MTN contract

I decided to take a contract as displayed on the September 2020 catalogue that offered 50Gigs day and 30 gigs night. On the first month, the data allocation was correct, thereafter I was put on a 40 gigs data contract.

I have queried the issue and it has been ongoing for more than a month. All the MTN agents are failing to assist me and they insist the data allocation is correct.

When I enquire about terminating the contract they avoid the question and say they will resolve the issue in 48 hours. Thereafter it's back to square 1.

The most useless service I have ever received.
