Terrible Service by Cell C

Regarding my previous review as follows:

This is a follow up to my previous complaint on the 22nd of February 2021. After my complaint was posted I received a phone call from Dume at Cell C, who insured me that the matter would now be finalised and that we would be reimbursed of the monies owed to us after cancelling our contract in November 2020. She then said I would be contacted within 24 Hours??? That of course never happened....

I would like it to be noted that they have continued to debit our account every month since then, although I was insured by Dume that the contract was cancelled in November 2020????

What is left that we can possible do??? the cell number is ***
