Telkom account

I had a landline with telkom and wifinetwork In Aug 2023 I asked them to cancel my line But instead it got suspended I received an account for R1770 which I paid in Oct but the service was in any case not restored I received an account 2months later again I phoned in and explained the situation to them accounts referred me to cancelations On 13th December I canceled the service again I received a bill again in January and are now handed over to a debt collector I cannot understand why they don't cancel my service as I requested They just tell me there is no record of me doing so After I paid the first outstanding amount of R1770 and my service has not been restored How can they keep on billing me I spent hours on the phone trying to reason with them and will end up paying again for something I did not use since August 2023 The debt collectors company promised me they will contact telkom and find out what's going on Today I received an sms to say a summons will follow
