Query not resolved!!!

<p> I contacted Cell C on the 26th of April to log a query for a recurring BIS plan that is showing on my account. I had an early upgrade in October last year and took out a Samsung phone which i havent used the Blackberry plan ever since. My New contract s****ed on the 1st of April and i noticed that I am paying for a BIS plan i dont use. Someone tried calling me on the 29th April, i was in meetings the entire day therefore i could not answer. I called back the 3rd May and the lady said me she will get someone to call me, she is going to "urge" the query. She did advise me that I will get the call the next day but to date i have not received any call. I also notice now that my Itemised billing was taken away. I checked last month as well there is no itemised billing and i always had 1. Query ***. I need this sorted out ASAP.</p>
