Bidvest Insurance is a ****

I bought a car in January. It was sold to me with tyre, rim and lost/damaged key insurance. Their policy says I'm cover 100% within 10000km from date of policy inception. The car was a demo car from Bidvest McCarthy Nissan so technically I'm the first owner. I got a puncture in February, I put in the claim and it was a whole lot of admin to get it processed. I had to do an affidavit from SAPS stating what happened, than I had to go to 1 of their chosen trusted tyre shops to get it assessed (at my own cost of course). Than the assessor takes pictures and fills the forms to send back to the insurance company. They approved my claim but only agreed to pay 30% due to tyre thread! My issue is that the policy than contradicts itself, 100% within 10000km from date of policy inception and than 30% because of tyre thread! I escalated the issue with their complaints department and I didn't get any correspondence for a full 2 weeks. I called back, spoke to Busi who initially assisted me. She escalated again with her manager, while I was holding the line (again at my own airtime cost). The manager shifted the blame to the dealership Bidvest McCarthy Nissan Randburg, saying they shouldn't have sold the car inclusive of the insurance since the tyres are worn out already. This was feedback that I am now overhearing on the phone, I did not speak directly with the manager. So I was told to take it up with the dealership and I refused. I am their client and I have a complaint sbout their product, if there is a third party thst needs to be involved than I believe they should do the run around. So Busi supposedly told her manager and she gave me an email address to send through the dealership personnel who assisted me. I provided them with their email and asked that they cc me on that email so to keep me updated. I'm very dissapointed because again I have been waiting for another 2 weeks to get correspondence and there is nothing.
