DOUBLE BILLING, BAD SERVICE

Ever since October 2013 I have had nothing but issues with MTN. It started with sim cards that was ported from Autopage to MTN. These ports was eventually done about 5 months after the request was done. Then to top it off I was double billed for these lines for 4 months. Neither MTN or Autopage wants to except responsibility on these charges. Its been 17 months since the porting request and no credits has been passed and nothing has been done to resolve the issue. Then I requested for another batch of lines to be ported in August 2014. This was only done in October 2014 and yet again, I am being double billed for these lines, and I am still being billed for these lines from both parties. Also the last batch of lines was ported to the wrong account at MTN. Then another batch of lines was requested for porting in November 2014 which is still not done. Then there are numerous requests for work that I needed done, and it is still not done, or had any response on when it will be done.<br> Looking forward to someone at MTN`s response?<br>
