CellC ****************

I have had a Data contract with cellc which has finished at the begining of January 2020 however cellc continued to bill me not even advising that the amount i was paying is 100% more then the data cost that was concurrent , None the less i had a call from a sales person advising that my contract has been finished and offered me a month to month Deal in which was R130 if not mistaken for the same amount of data i have agreed solely that this was a month to month and no strings attached package ( On recorded Line) he agreed i ended up using the Data that was offered for atleast a month therafter i did not want the deal soi just did not pay , To my surprise i was loaded this data every month on the sim that i wasnt even using or was not even paying for month in month out and now i sit with a hefty bill how is this possible?????/ as this is not a contract and if i dont pay Cell c should have suspended service immediatley due to is being a month to month deal i have followed up a number of times with regards to this matter and no response

Can someone, Anyone please advise to this bill and rectify as this is ****************
