MTN gives bad service

To who it may concern<br> <br> Please could someone from MTN assist me with the problem I have, I have no joy dealing with the call center and the MTN store at Clearwater mall. <br> <br> From March 2015 to date I have been receiving very high phone bills while having a capped MTN line which is at R500.00. March was R1432.82, June R2035.81, July R1784.61 this is what i am paying regardless of my line being capped. <br> When I spoke to Louise Ncube from the call center she has advised that I was being charged for data which is impossible as I buy all my own data with my fnb account, and i had sent her all the supporting documents to show this and the email sent from Mathilda Modjadji in the customer care department please note to date i have not heard a word from Louise or Mathilda after sending all the information required.<br> <br> Mtn at Clearwater mall had promised that the manager would contact me after speaking to Rossina at the shop i have still not heard from them. I personally feel that the service that MTN is providing to its customers is unsatisfactory and the worse service I have ever experienced. I would like a settlement letter from Mtn as i would like to move my business to CellC.
