Bring my phone to me, please!!!

Hi, on the 23/06/2015 my i phone cease to function. The touch pad was not working and I immediately sent the phone to the nearest Telkom since it was under warranty. They checked in my phone at the menlyn branch and I was informed I will received notification from the repairs department within a week. They only contacted me on 3 weeks later to inform me that my phone was not under warranty, which was obviously incorrect. Once proven wrong they informed me that there was a chip on the phone so I had to pay R4300 for repairs. I denied the quote and asked from my phone to be return. I paid the phone handling fee and sent the confirmation. On the 15/07/2015. I did not receive any feedback from the repairs department. I then went to to the menlyn branch and provided them with the confirmation of payment on the 29/07/2015 and I was informed that the phone should be received within 5 days. It is nearly 30 days later and I have not heard ANYTHING from Telkom. When I contact the call centre no one knows what to do and they put me on hold for 30min. I have also requested for settle to quotes for my phone as I am moving my business away!
