Telkom fibre

Hi I have logged a cancelation for fibre with telkom on the 17th November last day of service being the 17th December 2020. I have confirmed this with telkom staff on 15&17 December they have confirmed that it was auctioned for 23.59 pm 17th December. This morning 18 December I spent 3 hrs on the phone with them they are now telling me it would take up to 5days for this to be actioned. There service it just so shoddy I was told by another services provider that they do this in order for you not to cancel with them because you don't really want a break in your fibre service.
