Cancellation of ADSL Line

I went to Telkom Gateway store on the 19 Feb 2021 to cancel my ADSL internet as we have fiber and Telkom does not support fiber in in our area as I was told this by a consultant after inquiring. I was advised that Telkom will have to cancel my mail box as well and after the 30 notice period has expired I should come back and activate it. I agreed but I also advised I still require the copper line. Telkom agreed. I was sent a cancellation request case ***1 and ***3. I went back to Telkom gateway on the 24 March 2021 to re-activate my mailbox and the consultant Andile advised me that no progress has been made on my cancellation request as yet. He further escalated it case nos ***2 and ***5. I went back to on to the store on the 26 March as now my Telkom line had been cancelled. He advised that Telkom has Cancelled the land line as it was uneconomical to maintain. All I wanted was for Telkom to cancel my adsl only and provide me with my mailbox and landline which i had for many years. Now I have no services at all!! Should I as a customer require to cancel a service I need to provide 30 days notice - But telkom can cancel at anytime without notice.!!!!! Telkom with all the frustration you put me through please reconnect my copperline *** as I do not want the wireless device.
