MTN is the worst network

Sitting at MTN store once again, trying to sort out my wifi issues and all the additional charges they want me to pay when they canceled the contract earlier than agreed! I am taking time out of my study leave to fix this now because it just stopped working just after I received an sms that my order has been submitted (I did not order anything) shortly after that my wifi stopped. I am beyond annoyed at this point, I really don't know what do because my emails are being ignored! I can't wait for this awful contract to end so that I don't have to deal with this atrocious service.
