CELL C EXCLUSIVE BAD SERVICE

I was contacted by cell c and took out a data package of R220 for 50gig day and 50gig night. Money was deducted August 25th and Sept25th. On 1 Oct I received an SMS stating that "my monthly bill limit subscription & value is R417.99. You have R199.01 remaining to use". I immediately contacted the call center and they told me i have an open line, which I never requested as this package was for my 13year old daughter for school research work and i told the agent I don't mind if the line is blocked after 50 gigs are used up. The supervisor promised to phone me back which never happened. i phoned again to confirm if the line was closed and they said the line was def closed and the bill will stop when 50gigs was reached. On Oct 25th I had the shock of my life with a deduction from Cell c of R3300. I reversed it and phone Cell C and again I was told the line was closed. I decide to write to complaints department via Email, where communication was extremely poor as they take up to 2weeks to respond to my emails. I communicated with Lesego from Cell c exclusive "please note that we received communication that you have a problem with the limit set on your account" which was not my complaint by the way, I complained that I was never told I have an open line and i questioned if my bill was R499 on 1 Oct when they closed it, why did the bill jump to R3300 on 25 Oct. The complaint was handed over to Doreen From Cell c Exclusive and on 27 Oct she wrote that my account limit was set to R219, so I requested to listen to the recording, on 9 Nov the recording was sent to Golden walk cellc in Germiston, when I got there we were not able to listen to the recording as there was some issue with the recording. Doreen advised that Collections dept. will contact me to make arrangements for payment,. I requested cancellation of the contract and have not been using the router since October, I also requested the contacts of the Ombudsman but Cell c Exclusive has since stopped responding to my emails, Koketso from Cell c exclusive was requested to assist me Ombudsman details but since has not responded. I do not know since I have tried everything to resolve this, nobody is phoning me since I have not been paying and not using the router. I was willing to settle the R499 but I want to know where the R3300 bill is coming from when i took out a 50gig package.
