Cancellation request: Not finalised for months - UNEXCEPTABLE

I have submitted a cancellation request prior to 20 April 2020 with a 30 day notice period. To date the service is still active and I am being billed which is unacceptable and I am not willing to pay for something that should be cancelled. I have spoken to many Telkom agents who all promised that the cancellation is being finalized "tomorrow" and i guess tomorrow never came.

Reference Numbers for cancellation: ***0 - received via sms on 20 April ***55 - received via sms on 20 April ***6 - received telephonically on 20 May 2020 I Spoke to Paulisa on 1 June who also advised that I do not need to make any payments to Telkom

Please have this resolved immediately and my account credited and send confirmation that this is done
