Overcharged Data Bill

I tried addressing the issue a few months back with the call center (2 days before the MTN call-centre strike) & then when their call centre was closed & I could no longer reach anyone, I had no choice but to go into an MTN store (Greenstone Shopping Centre) where the gentleman promised me a refund & said he understood that MTN was in the wrong. I then struggled to get a hold of him for feedback & started venting my concerns to MTN on Twitter (from around 3 July- I have the records). They sent me direct messages making promises of sorting it out & still nothing happened. When I continued to make some noise about it they asked me to send them my ID number & I refused saying that I was not comfortable transferring such confidential information on a public social media platform. I asked them to get someone to call me. Nobody did.<br> <br> I have not heard back from anyone & was promised feedback !<br> MTN has overcharged me on my data account despite the fact that my online behavior has not changed & I could hardly log on to their network with my laptop, which is the device being overcharged!
