Stop debiting me for insurance I asked to be canceled

Good morning I have been a client of Telkom for more than a decade. A year doesn't end without a complaint. This year I woke you to my lines been closed. My debit order is always done on time, this month it's supposed to be done tomorrow 1st of March. All because of an insurance that I canceled in 2022. I reversed the amount thinking that will help no it made matters worse. I had 3 devices insured with Telkom Amin insurance. When I list one them they said it was cancelled, fine. I sent an email canceling all the insurance because I don't even have the devices anymore. Telkom Admin plus acknowledged. #Telkom kept on billing me, I called they said its not them.its Admin plus, Admin plus said it's Telkom. They are tarnishing my credit record. They are frustrating me. I don't know what to do anymore. I'm paying insurance for what I don't have and they have emails stating my cancelation. That money is for my children s food. Please help.
