No support, no help. Just charging me money

Horrible experience with MTN. I will not renew all continue my contract with them. Upgrade online trough a 3rd party and they refused to assist with my horrible experience I am have. Got a new phone with issue straight out the box been having issue and they told me to return it. Now they it will take 30 to 60 days for them to replace this phone with a new one. Even tho the phone is 3 days old. MTN says there is nothing they can do and refuse to assist with there own 3rd party. Regretting MTN after being a customer for the last 4 years. Don't waist your time. They will send your trough hoops to get assistance and non of them know the right process. Not the people in store or one the phone. Everyone giving me a new process to follow each time I call. Took 2 days to get to a point. Now if I cancel they want to charge me the full price of a phone that is in there repair centre.
