Unacceptable

I received a call from MTN a few months back. The sales representative interested me in a Samsung deal which according to him, came with two (2) gold Samsung Z2 mobile phones. However, I received one black Z2 and the other gold. Clearly this wasn’t what I had agreed upon. I then called MTN and requested that they either to give me the initial color we had agreed upon or terminate the suppose contract. Spoke to a gentleman by the name Ryan who advised me to return the phones to their nearest branch, which I did . Now I’ve got no phones from MTN yet month to month I’m still debited! Paying for merchandise I have no of, unacceptable if you ask me. This issue needs to be resolved.
