MTN AIRTIME THEFT

On the 19th of January 2022,i loaded R100.00 airtime and bought R50.00 data what happened afterwards is a total lie from MTN. I am using a dual sim phone, their explanation is that I called my other on the same phone for 15 minutes which is nonsense it can't never happen. #MTN stole my R35 Airtime under falls pretence.
