Receiving phone calls before 08:00 in the morning for "outstanding money"

In November 2020 I cancelled my DSTV subscription and all were fine.

8 months later on a Saturday morning at 07:15, my phone rang and I have been woken up receiving a call from a Cellphone number stating that I owe DSTV / Multchoice money. What the heck is wrong with you? 1. You won't keep my package active if I owe you money. 2. Can't you have the decency to call me from your main number DURING OFFICE hours if there is a problem?

This is unprofessional and sly....

Please fix your **** system and stop bugging me on a Saturday morning before 08:00
