Cell C the worst company out

I have been through 7 different people trying to get to the cellc legal department. I have waited on the phone for 20 minutes at a time and still cannot get through. Cellc is one of the worst companies out there. Their customer service consultants are rude and unhelpful. They shove you from one to the next to avoid answering any questions. To get rid of you they simply put you through to the next person and inevitably you land up phoning back. We had a two year contract with c fibre which ended 30.09.2019. before the time we cancelled the contract o the 13.09.2019. We sent a mail to cancel the service. Reason being they could not provide us with fibre to our new home and therefore we could not make use of their services. Since our cancellation they have tried monthly to deduct money off our account needless to say we contacted them every month for them to explain why. Their excuse is someone authorized them to bill us on monthly basis for extra data. That someone was not us yet they cannot provide any information further. All I can say is it was not us as we have LAN unlimited through a provider that really knows what they are doing and their billing is one hundred percent correct each month. We have been placed on ITC for cell c incompetence yet when you try and contact the legal department to assist you cannot get through to a single person. Failing someone contacting us to resolve we will be forced to go to the ombud with all our documents and letter of cancellation from September 2019 to resolve. Cell c is the worst company I have ever had dealings with. Staff ***********, management non existent. The legal department is obviously also not interested as they clearly don't investigate before slapping you into ITC.
