Horrible customer service

I’ve never come across a business that take its time to respond to its customers the way MTN does. They will literally take weeks to tend to your query and it won’t even be resolved. And dare you call in to get assistance, their agents sound like they don’t even want to help or comprehend what you’re asking of them. Their app is Just as useless, they say you can change your banking details there but that option doesn’t even work. I cannot wait for my contract to come to an end that I can rather join another network provider that I know responds to its customers.
