Bad network and customer service

I am a contract customer of MTN, on the 14th I received my R100+ airtime as always at that time I had about 150 MB data bundles positive balance, just after I received my airtime I switched off my phone and placed it on charge. The following day at about 11:00 I switched it on and checked my massages, then left the phone.

At about 15:00 I wanted to call someone, and when I did I found that my airtime balance was R00.00 and had no data available.

I had called MTN and the lady assisting me had logged a call with Tec support promising me a reference sms and a call back within a few minutes which never materialized, on the 7th of October I had called them again(almost 3 weeks later) I was told that it was not attended to, now I called them after a month and the consultant that just assisted me tells me that the report she is looking at on her screen says I had no balance on my account for the two days 14/15 September. And this is the response that I get via email showing me something:
