Complaint about Billing on my account

Good day,<br> <br> I logged a query with cell-c on the 23rd of January 2015 about the Billing in my account. at the end November and in December i was billed 279 for my account and now end of Jan same amount. I logged to understand why i was billed so much. Till today no one has gotten back to me. <br> i called on the 26th of to advise that my cell phone will not be working but i will be available on my work number to my surprise Tshepo Lekopa called me on my cell phone later that day. i have been following up every day since I logged the query and still have not received feedback. I have sent emails to Tshepo and he has not even acknowledged that he received my mail. the last call I made was on Friday the 30th, the contact centre agent advised me that since my query was over the turn around time, she will be forwarding it to the department that deals with query that are overdue. I still haven't received any phone calls from them as well<br> <br> I am very disappointed with the service i am receiving with Cellc.<br> can someone call me on my cell phone now as it is working ***<br> Ref ***
