Vodacom insurance useless - don't pay.

I have submitted and insurance claim for my phone to be repaired on 25 March. Vodacom acknowledged receipt of the email. I have subsequently requested them to respond to my claim 8 times, with no response. When I went to the Vodacom shop, they said I had to wait 21 days for my phone to be repaired - what nonsense. Which professional person can go without a phone for 21 days. They then said the option is that I get a quote from a company that can do repairs which is what I did - I-Fundi i Durban North does repairs for Vodacom. So now, do I just have to wait ad-infinitum until Vodacom decides that I can be responded to. I-Fundi can repair the phone on site. Once that is done, I need an upgrade, but apparently Vodacom cannot do that for me and repair my phone.
