Can i have my billing sorted or contract cancelled

<p>I’m very disappointed with the service I get from Cell C lately, I have been using cell c for over 10 years with no complain but ever since they change their packages I’m so disappointed. I have made an early upgrade on one my contract (073 ********** ) which took place as discussed on the 10 August 2016, I had over two months unused services which they took as forfeited due to new contract kick in, come the 1st of September they debited me for old contract for the services I never had a chance to use. I called them to find out what’s going on Musa Baholo from the billing department failed to explain me, call was escalated further to Lungi after writing to hello peter who called and promised me that I was going to be prorated and credit will be used for next month as a result of being debited the outstanding. 1st of October 2016 full amount for old contract was debited again. Can I please have someone with experience to call me and explain what happened and refund me what was debited incorrectly, Please don’t tell me this will be left as a credit as empty promise was made before. This made me doubt my billing with cell c anymore, am I being ripped-off? Please call me on ********** 378.</p>
