Cell C is useless

Cell C is the biggest **** ever after I gave them notice after my 24 month period that I do not wish to carry on with my lte contract they keep on trying to debate my account telling me that I owe them money for the month to month benefits I did not agree too a month to month contract from my side I emailed and phone the call center and gave them notice but they stil try to ****** money out off me they do nor respond to my emails ore phone back when u submit a query. I will give them a -0. I have been trying to resolve the issue from July 2022 it now November and still have not been solved
