My mate had his car with Shannon's.
It was stollen and torched and he got his claim, but only after they had a PI on him for a month, then had to wait for his payment for another month or so and now they say that they will never insure him again. Wasn't anything dodgy and the PI said everything was legit.
I've said it in here god know's how many time's but Wesfarmers is the best insurence company I've been with and my parents are with them too and also agree.
I had nearly 5k damage to my old 32 from some kent's trying to break into it. They said that I need to get 2 quotes from 2 different places and I pick which place that I wanted my car at (not them)
Also, they cleared the costs through the crash shop on the spot with their guy and repairs started straight away! Also, in the time it took me to go around and get the quotes, they paid for the door handle to get fixed on my car so I could keep using it till I get the rest of the car fixed.
Also offered free rental car to me for the time of the car being fixed, but I got one from the crash shop anyways.
On top of all this. I was only 17 when I got my insurence with them, and only changed me $700 full comp with a $500 excess. After I claimed I thought it would go up and it didn't. The next year it went to $498 and $400 excess.
The more shit you got insured with them the better it will all work out for you.
