Nandipha hanged up my call without assisting me

I am very unhappy with MTN service, I have a contract the expired in March but up to this day they are failing to cancel it, I always call them and hold the line for a very long time but I don't get assistance they just hang up my call.<br> <br> I want MTN to cancel the contract in question with immediate effect because I am paying for nothing, their network sucks and I always forfeit my data, their customer service is very bad and they forget that customers must be their first priority. should I not pay my account I will be blacklisted in a second but they fail to do simple thing.<br> <br> I am very unhappy and wish that they resolve this with immediate effect because I can no longer pay for something that's useless, I am tired of being ****** on daylight.<br> <br> I've been calling them since March but they are not helping they just keep on taking my money for nothing
