MTN You can Keep your Atrocious Service.

I have installed MTN internet solutions to 3 of my homes. Last week, because of my existing accounts, I added my primary residence as well. Now one week later, I have unreliable service, calling customer care is useless because none of the numbers actually work and generally shocking service from MTN. I've had Cell C Fibre at another property for 8 years, never had anything like what I see regularly from MTN. I am ready to cancel all services and even incur the costs.....except, there's NO CUSTOMER CARE to assist me to do even that.
