Worse treatment by Budget insurance

I put in a claim for small dent, I then received a letter that my claim was rejected. This letter was disturbing because it listed all generic reasons why a claim could be rejected, it however fail to be specific to my claim. Previously I was told a dent must not be more than 30cm, now my dent is only 22cm. Then on the 9th of October 11:35, I called their call centre only to be attended by a rude gentleman. I have never experience such rudeness from a call centre who further **** that the insurance contacted me. Upon posing questions he said by dent has a paint pilling off and put it to him that there is no such in my policy which can cause my claim to be rejected. He dropped the call on me. Really I have been with Budget for more than 5 years to be treated like this its a shame. They really take customers for a ride with their value added products. How to they employ such rude call centre attendants. The only solance I have is to cancel policy but i learnt a vaulable lesson with this company . To think that it includes to many insurances companies under their group its a shame for Telesure.
