Poor service delivery

On the 21st of April 2019, I made a some few calls, then did a balance enquiry which said I have a negative balance of -R0.24 I was a bit shocked as I didn't sign up for any extra time with MTN. I then bought airtime for R7 to see what will happen, I checked the balance and It was subtracted by what I supposedly owe MTN. This really came as a shock. I called MTN and spoke to two ladies one of them was Nothando I think. They both told me two different stories. I asked for one of them to send me call reference, unfortunately I am still waiting.

I then took it upon myself to go to twitter to at least get help there and even there I wasn't assisted, I was just told what I know that I don't have extra time.

The unfortunate thing is that, this matter is persisting. I bought airtime for R6 there after, MTN balance enquiry told me I owe them -R4.26 and every time I bought airtime this would be deducted from my account. I restarted my device more that once to see if I would get different results and still nothing.

I am even scared to purchase airtime now as MTN keeps on deducting from my account. I am really not pleased with this service. I hope someone, someday decides to take me serious.
