Tired of waiting. Need answers NOW!

I upgraded from a Samsung to an Iphone. I had the phone for a week and a day and the screen just cracked. I went to Autopage in Witbank at The Ridge mall to give the phone in for repairs, the lady told me I should rather come back the next day because the guy that helped me with the contract wasn't there and it will be best he helped me.<br> <br> I went back to Autopage to give the phone to the guy that helped me with the contract. Then the system didn't pick up the phone model to book the phone in. He asked me to come back on Saturday because the system only picks up the phones from 2 weeks old. I went back the Saturday, and booked the phone in, but the system still couldn't pick up the model of the phone. The guy said I must leave the phone with him, he will send them an email and the repairs people will open a job number.<br> <br> The guy sent me the job card to sign and I sent it back to him. Since then he and the manager struggled to get feedback from MTN where the phone is at the moment, to be released. It is now more than 3 months that I am paying for a phone I don't have.<br> <br> I have emailed the service center to cancel my contract and they still haven't got back to me after 8 days.
