Disgusting service

The worst network in the land! I regret ever joining MTN. I haven't been receiving calls for the past 7 days and every time I call I get told that the matter is getting escalated. I don't know how many times a simple problem needs to be escalated. I cancelled my contract on the 10th of July 2020 and the stupid call centre agent didn't cancel I had to call again on the 21st of July to make sure all is cancelled that's when I started experiencing this issue. I keep calling and i get told that they have sent my ticket to the Wholesale billing department and there is no number for the. This service provider is by far the worst!
