TERRIBLE SERVICE

This year in February a guy called me from supersonic to renew my existing data contract with mtn. I was supposed to receive 60gigs every month. I still have not received the agreed data. I tried canceling my existing contract with mtn as it came to an end in February anyways and I was told that my contract was extended and will only end February 2022. I'm failing to understand how because I am not receiving the data I agreed to this year. Your consultants can't even help me. I want my contract canceled AND I WILL NOT OAY ANY CANCELATION FEES!!
