Getmore at CellC ignoring Cancellation Instruction

I had a telephonic conversation with Getmore at CellC some time back asking them to remove my Getmore Service. Unfortunately I did not do it over email and I cannot remember when I communicated with them on this issue. I think it was at least 8 month s ago. I instructed them to stop the service and to stop billing me every month. They still haven't done it and it is now 30 June 2020. Neither have I ever used the service. So please Getmore - stop taking money out of my account every month - money that you are not entitled to - and cancel my service immediately. If Getmore is doing this to me I am sure that there are lots and lots of people out there that they are also billing post a cancellation instruction.
