Pathetic Service from MTN....USD ***

I went into the branch in Summerstrand, Port Elizabeth to get help with a WiFi router/****le. The person who tried to help me was Eugene at the branch. He called the phone center to try and resolve my query. There seemed to be a huge passing the buck exercise at the call center. He was handed from one person to the next but to no avail. It has now been almost 4 months and my query is still not resolved. I have been paying an amount of R189.00 per month but am still unable to use the ****le to get access to the internet. This has been really frustrating and irritating. Is there anyone who can help?
