Fed Up with Cellc

I am so fed up with cellc. Since the 14th of October 2015 I am battling to sort my account out. I spoke to numeruos people and now they say that the case is close. Yesterday they block my account. My account was for R4000.00 for end of October which my account was never more than R700.00 a month. they say that it was my data that was running at the back ground and that hapened at night while I was sleeping. I've got this phone for over a year and I did not put my data off at all. then in October my bill was for R4000. since November they take all the money off my bank account and then I reverse the money back. I eft only R700 back to them and on the email I say I wil carry on paying this amount until my account is sorted out. I NEED TO MAKE CALLS FOR I AM RUNNING A BUSINESS. they don't give a damn about there clients. i am a client since 2006 and never had problems with cellc. NEW REF NUMBER IS ***
