Failure to resolve a 7 month's query

I reported my modern to be ****** on the 22nd of Jan 2015 and requested that it be stopped since the ***** was using it. It was only stopped last month after calling them a million times. I further logged 3 queries for a refund but no one is assisting. No one has called me to even give feedback. Cell C has really made me feel small and helpless. I can't even be given a letter of deadlock. I have waited for 3 weeks to receive the manager call. TALK ABOUT NOT TAKING ME A CUSTOMER SERIOUS
