Mobile Contract Cancellation

My mobile contract with Telkom ended on 25/02/2018.

I submitted cancellation papers and asked for the number to be switched to prepaid on 01/03/2018.

I have been calling in and each agent says and does the same thing, "we have escalated the matter". I was told it takes 21 working days which has passed. I was also told numerous times that it takes 24 to 48 hours which has also passed.

Why is it so difficult to switch the number to prepaid. It took 5 minutes to open up my Wi-Fi contract in April 2018 but switching my number to prepaid is such a mission.

There has been absolutely no joy in this regard. In the interim, I have been billed for the two months and now going on a third month.

Very disappointing!!!
