I am giving them 1 star because that is the minimum possible else I would have given them 0 stars. Cleartrip is a cheap company trying to entice money out of their customers one way or the other. While booking a flight ticket, they have an option to select insurance for the trip which by default is checked. So in the clutter of other information on their web page, if you miss noticing that the check box for insurance is checked, you inadvertently will end up buying the insurance. It happened with me, and when I called them within 5 minutes of booking the ticket to cancel the insurance, I was told that it is non-refundable. Since insurance is not a free service, a customer must explicitly and knowingly select the insurance instead of having it selected as default. I find their business practice to be deceptive and unethical. To top, their customer service left a lot to be desired. Needless to say I won't be doing any business with them in future.
