Telkom landline saga...5 years later!

It has now been almost 5 years that I had informed Telkom to cancel and discontinue my landline. In response I received a SMS from them on 21 August 2019 at 15h30 (thank God I have kept that record!) which said the following: "Dear customer, We acknowledge your request to cancel your services. We are busy working through the application and one of our agents will be in contact with you before close of business to finalise the process. If we are unable to contact you we will send you an email to confirm cancellation." I did receive a call later from their agents requesting which landline I wanted to cancel (I had 2 landlines- the other was cancelled in the same manner but with any trouble in April 2020), and confirmed the *** to be cancelled. Later that day at home I checked and confirmed that my line was duly cancelled.

Since that time I have been pestered by more than 4 collection agencies as well 3 attorneys with demands for payment...after a while they all give up and now the 4th attorney based in Durban keeps pestering me and demanding payment. So now instead of the statements keep coming month by month... I am still receiving telephonic demands to pay the arrear rentals for which I am clearly not responsible. I obtained legal advice and they informed me that Telkom and their lawyers do not stand an "icicle's chance in hell" in light of the communication I have from them.
