While browsing on google I came across this result where people have written not so good words about Royal Sundarams car insurance policy and I was pretty surprised by reading all these reviews. I have had a rather different experience with them which was at the positive side.
I had acquired a car policy from them about a year ago and what attracted me was their quick claim settlement within two working days and I thought to give it a try. They were true to their words by settling all my claim with 1-2 days for my car damages that happened due to a small accident(I was not a good driver then.. ;)). I think you should call their helpline number which is 186042500** as this number always helped me for any queries I had.
