MTN: 3 months, 3 phone calls, still charged for 1gb extra

MTN: this was the third month now that i was charge for 1gb data extra that i have not received, i have phoned MTN service provider to sort out the problem, then i get the sms that the problem was resolved and that they will crediet me, but this morning was the last stroll, paying for something that you didnt ask for in the first place, and then you dont get it also... thinking of stopping my contract. MTN ylu4 service suck, sort this out
