Disgusting customer service

I have a made a cancellation request of 2 of my fiber lines as I would no longer need them. I was told to await 48h for some sort of feedback/confirmation thereof. It has been TEN BUSINESS DAYS since, I have called Vodacom’s fiber hotline at least 4 times, sent the same amount of emails at the very least and all of it falling on deaf ears. Zero acknowledgement from the institution. Nothing but “please allow some time and call us back”. Why do I need to call you multiple times if your SLA’s state that I will RECEIVE feedback, and not chase after it? Absolutely disgusting service.
