I want my money back

I bought 1Gig from my capitec app on Monday, my data just disappeared, I thought it was me maybe something was updating in the back round. Tuesday morning I bought the 2gigX 7days for R200 to date I have not received any data bundles, I have called mtn customer care spoke to Terry and she advised that she would send me an sms on how to restrict apps updating on my phone, I told Terry that I have been using my Telkom wifi and I have not used the mtn data, she advised that they have a system issue she can't see what's utilizing my data but should I not receive the sms I must call back in the next 30min,i said I would call the following day.

The next day no data, I called MTN and spoke to a rude consultant by the name of Promise, I politely explained to her why I was calling and she tells me I used my data on YouTube, Facebook, Google maps and Watsapp. I explained to this lady that I have been using my wifi and at no point have I been able to use their data, and she told me she can't just assume things and say things out of her mind, I told her I had been waiting for the sms that Terry said I would get and she said to me, she will not be sending me an sms I must get my background data, I used my data.

Today is a new day again no data loaded, my phone is still connected to my Telkom wifi, to top it off I have never received any notifications from mtn to say i have used any data or that its deleted. I want my R270 that I spent on mtn and I am porting to another network.

I am honestly disgusted and disappointed by the service provided by MTN. I have been a loyal customer since I was in high school but this is just the last straw.

I can't let my hard earned money to go down the drain.

FYI- Terry provide great service to me.
