We have been insuring our 3 cars with Shannon s since 2007.
Never made a claim until yesterday.
This is what happened -
One of our cars was parked on the street while we went to do our shopping.
While we were away, someone backed into our vehicle and damaged the tail light.
There were no witnesses and no one owned up to doing the damage.
Shannon s said I had to pay the full $600 excess because we don t have the guilty
person s Rego number or any other particulars!
How could we, when we didn t witness the accident???
The quote for getting the tail light fixed is $500. So, I m not paying for any excess.
What I m going to do is CANCEL all my 3 car insurances with Shannon s.
NEVER INSURE WITH SHANNONS.
