MTN Direct Bad Service

I app**** for a cellphone contract iPhone 7 and I received it yesterday 06/10/2020. it is now not connecting to the server and decided to return it. Called MTN Direct because I did my application with them *** and was told to return it to any MTN store, closest was MTN Carlton Centre. the lady that was assisting me was so helpful, however the system did not accept my return and was then told to expect a call from my sales person from MTN. I then decided to call MTN Direct and was told to return my phone to an MTN store, told them that I was told at the store that MTN Direct was gonna organise form my phone to be fetched from me. I then gave the consultant my ID number for her to check the person I did the application with. I was told that I did the application with CCI and would be transferred to them, their phone got cut off. called *** again and they finally managed to transfer me to this CCI. My concern is that I'm being told about CCI whereas the time I was applying I was never told of CCI or was never given an option to choose between CCI and MTN Direct. when I want to return the phone I'm being sent from pillar to post and given excuses. I chose MTN because of their stela service, I am now extremely disappointed.
