Telkom ADSL cancellation

I have formally requested cancellation of my ADSL line on 26 March 2020 and sent my cancellation request to *** and to date I have not received any confirmation or acknowledgement from Telkom. I stated in my initial email that the month of April is to be used as my 30 day cancellation notice period. To be clear, I will pay the full amount due to Telkom at the end of April 2020 but that's where it ends. As from 01 May 2020 I will not make any further payments to Telkom as my cancellation notice period of time would have lapsed.

I require immediate confirmation that my instructions have been received and attended to. Based on my readings of other reviews on the Telkom cancellation, I do not want to go through what others have gone through.
