Poor Service

I have been with MTN for years and recently someone opened a ********** data bundle on my name. I have reported this to MTN however, no one call me back. The call centre is useless and I have asked to speak to management but they are not available, they also don't return my calls. The ***** on this bundle account has been going on for more than 3 months. I must proof to MTN I didn't take out the bundle, how ridiculous is that...why don't MTN proof to me and provide me with the signed documents I have signed for this bundle. I had to send MTN a affidavit, ID and proof of residence in order for them to investigate. I have done that and still no response. Today MTN suspend my phone account because I didn't pay the ********** bundle account. Is this the way MTN treat their customers....????Pathetic
