Quality Insurance service

I wanted to let the masses know of a good insurance company story.
In Apr 08 I brought a new 4 WD and I thought that at the time I cancelled the insurance on the old truck.
I pay my insurances by the month and I then got the renewal for old policy in Feb 09, which I was sure I had cancelled and therefore should not have received the renewal. I rang the company to enquire as to the cancelling of the old policy and was told that they had no record of the cancellation.
I then cancelled the policy from that date.
When the cancellation advice arrived in the mail and upon reflection of what had transpired I rang them again and subsequently received a cheque for 640.00 odd dollars being a refund for the outstanding credit on the policy since the date I thought I had cancelled the policy.
CGU had no responsibility to do this as I provided no formal correspondence to them in the first place.
They simply took what I was saying on the phone on face value and provided the refund.
