Vodacom insurance not fulfilling its promise

I took out an insurance for the phone on contract with them.... Boom my phone just switched off in 3months and I took it back to the store because I had an insurance only to be told after a month that my claim has been declined because I did insert the SIM into the phone in question. I then informed them that the consultant that was assisting me didn't inform me that the phone had to always use the Vodacom contract SIM. So now I have since been given the run around on receiving the recordings and a resolution on my claim enquiry.
