Travel Claims Facilities - is this a scam?

Hi, my parents recently had to cancel their holiday due to illness. They had insured the holiday with Allianz Insurance and have received the documents to complete and this was the company they had insured with. However, they have also received documents through from a company called Travel Claims Insurance with no reference to their policy, etc - just a claim form - it seems a bit odd that this additional company have sent through documents. Has anyone else heard of this company ? I suspect this is just the mail equivalent of the 'we heard you'd been in a car accident' phone calls but the last thing I want to do is jeopardise their refund by not completing all the correct documentation.
