Cancellation of ADL line from TELKOM.

What do I do to cancel my ADSL with Telkom and get a stand alone e-mail account. On 16 May I phoned to cancel my ADSL line. Was told that I have to give 1 month's notice. Told to call on the 16 July 2020 to activate a stand alone e-mail. Phoned 16 July 20, nothing done ADSL still active.Put through to sales, billing, cancellation etc Spent 55minutes on the line. Nothing. 17 July went to Telkom shop in Kenilworth Centre. Told nothing done and I have to give another month's notice. This is ridiculous. Assured me that an agent will call me. Still waiting. 20 July called and was told that due to technical problems on their side they are unable to cancell and to call next day. 21 July Mandy escalated the cancellation and that an agent will call within 48 hours to activate the stand alone e-mail.Went onto their website to chat to an agent. Still waiting for the "Friendly" agent. 30 July called and was told that it has been escalated and that she will once again escalate it and that someone will call me to activate the e-mail. This sucks as Telkom is expecting me to pay for another month. I have read many complaints but never thought it would happen to me. Is this how they treat their customers? I have wifi at home so do not need the ADSL. why can't thy do what is requested?
