MTN worst servise ever

Got a call from MTN selling a contract last year, I was advised that all calls are recorded and if that was the case I wouldn't be writing this complain. My contract which was supposed to be R189 monthly for a Huwie device however on the 22 November 2018, 2 handset were delivered with 4 sim cards which is something i didnt sign up for. Yesterday i receive an inv for R1400.00 something else that i did not agree to as my contract suppose to be on Top up. The call center agents are rude and half of the time they dont know what they're talking about. This is the worse service ever and i will be logging this with ICASA cause its a BIG MESS done by your staff. I dont want this contract anymore cause its not what i agreed on.
