I booked my phone for OBF a month only to find out it has just been booked today for repairs.

I bought a phone on contract at Telkom mobile, Kollonade shopping centre on 22 February 2015 but within a period of a day the phone went off. I took it back the following day, only to find out that they couldn't book the phone as they were offline. They sent me to Telkom dirent, I was helped by Loutjie. He made a copy of my receipt and took the original to apparently book my phone for OBF. Last week, I went to check on my phone but they couldn't trace it. When i went back today, I was given a document showing that my phone was only booked today for repairs after almost a month. And why was it booked for repairs anyway because the phone was brought back within 7days of received date? I'm expecting answers from Telkom because I won't pay for a phone that I didn't even use. And again, I expect a new phone because I brought it within the given period. It is not my fault that the staff member booked my phone after a month from the day I brought the phone. What ****es me of the most is that they guy doesn't even have a record of the day i brought the phone.
