Upgrade gone wrong

CallForce contacted me about my MTN upgrade. I asked the agent about 5 times if it was a certian size phone which she and the manager confirmed. When I recieved my phone it was the incorrect size. They then said they would collect and reverse the contract. I waited a whole week for collection only to recieve a call a week later stating they dont do collections anymore (but their agent said they would collect) and that I need to return the phone to a MTN store.

I managed to return the phone but now I am still sitting with the upgared contract that needs to be reversed. No one at CallForce returns my mails. The phone isnt even ringing today. I can forsee me paying a contract with no new phone for months on end beofre this gets resolved.

DO NOT go therough CallForce for anything
