MTN failure to honour customers

Hi, I have a serious and ongoing query and dissatisfied with the services I'm receiving from mtn South Africa... I have two contracts with them, one is a cellphone contract which I'm paying R599 and the other one is for Wi-Fi. My complaint is regarding the cellphone contract, in January 2020 I got an sms to confirm that I have been credited with my normal monthly package of airtime, data and sms. But to date I haven't received it and apparently they claim that I received the package and even used it which is totally incorrect. On one of the claims they say I contacted a number and spoke for more than an hour but my contract only gives me 50 minutes of airtime so do I speak for 60 minutes when I'm given 50 minutes, and they don't even explain as to how I used up 500mb and 50 sms in that period. And I have never defaulted on the monthly payments. Hello Peter please help me get my package or they must do something as its now over 2 months now being told that the manager is looking into the issue. From Phetso Motwe
