The absolute worst service

I have been trying to cancel my contract with MTN since the 12th of January 2021. I have phoned numerous times and at different times of the day with no answer. I find it extremely hard to believe that the only department that works with cancelations has a high call volume from 8 am to 4 pm. How many cancelations are you getting in a day then?? It's obviously a terrible idea to have call center people work from home. Also, why on earth is there only one department that works with cancelations??? Why can't the people who work with the upgrades also do cancelations, especially at the MTN store, it makes no sense.. I'm not impressed with the service I have received and I will not recommend MTN to anyone ever.
