The demand for Payment of Service not provided!!

I have been battling with Telkom and it's appointed lawyers from March 2021 and up till today I am being threatened of being blacklisted and legal action taken against me. I took a landline over from the previous owner of a shop I bought in Cradock in the Eastern Cape. The transfer of ownership was approved by Telkom and my line worked very good for years. I then app**** through MWeb to have ADSL internet. This was approved and installed and worked very well for a number of years.In 2021 I decided to cut my costs and sent an email to Telkom to disconnect my service. They informed me that although I had a service from them they could not do so because I first had to apply to MWEB to discontinue the internet (ADSL). I did as instructed. MWeb required a one months notice period and it was agreed that they would inform Telkom of my request. After that was done, Telkom would then disconnect my landline number***). I decided to completely not use the line and removed the telephone instrument. Telkom was still sending me invoices with zero usage but rental being charged. There was no charges from MWeb as they discontinued the ADSL and informed Telkom of this. I have many emails of discussions with the accounts department of Telkom trying to sort out this account. They denied having received the discontinuing letter from MWeb and kept on sending invoices and demanding payment for services not provided!! During this time a big truck broke the overhead Telkom cable. A Telkom contractor also came along and removed what was left of the cable. They also removed the Telkom pole (that used to provide my service). All this time I explained Telkom what was happening. Many months after this I received a letter of demand from Telkom for a few thousand rand from their credit accounts manager. I again explained this rediculous situation but to no avail. I then started receiving telephone calls and messages from different lawyers demanding payment for a service discontinued years ago. I have the email from Telkom admitting to the letter of MWEB informing them of the discontinuing. It is dated 30th November 2021 and informing me that they would backdate the disconnection to 17th February 2021.This never happened. Lawyers are still harassing me and demanding R3 999!! A few lawyers that were appointed by Telkom quit after perusing the emails I shared with them. New lawyers have been appointed and the fight is still continuing. After many phone calls, messages and emails this problem have not been solved.
