OVER CHARGING

It is now 11 moths since I start complaining that MTN is over charging me for a service I do not received. (75MB Recurring HYB @ R 25.44). After numerous e-mail and promise's from MTN, MTN is still not willing or competent to resolve my problem. They did agree that it is their problem but it just don't get resolved. I did send MTN customer care an e-mail on 15-Sep-15 but they still did not respond, now they are threating me to block my phones if I don't pay the outstanding R50.93. I also registered a complaint with the Consumer Goods & Services Ombud, and I am still awaiting their responds. When looking at all the complains on Hello Peter it seems that their it an serious problem at MTN.
