Please repair my phone

Hi<br> I took my phone inn for repairs on the 19/01/2016 for repairs at Foschini Durban Central, I had to go in every week to check if its back but with no luck. I then went back on the 17/02/2016 and the guy that helped called Vodacom Repair center who that advised that they have not received it. We then had to call courier guys for them to send us the proof that Vodacom received it, it was sent to Vodacom that on the 19/02/2016 I went to collect it I was then told that they can't fix it due to physical damage. Well I failed to understand that it 2 days they concluded that it can't be fixed after one month of submitting the phone. They I told Foschini that I want claim as I took out insurance when I bought the phone. On the 23/02/2016 I went to check for my claim and the insurance company then told me that Im not insured If I am I should bring my papers that were signed. I went back on the 03/03/20116 I went back the documentation and to my surprise I was advised that the lady that helped me when I bought the phone in Gateway didn't send the documents to the insurance guys. Now Im stuck with a dead phone that I'm still paying for. Please assist.
