When travelers have a travel insurance claim denied, they could have HTH complaints. They could file a complaint with the state department of insurance, however, if the policy was purchased from Squaremouth, the traveler has another resource. The traveler can request Squaremouth mediate on their behalf with the Zero Complaint Guarantee. This promises to investigate a client’s complaint to try and resolve the matter with the travel insurance carrier. Unless the carrier provides a solution satisfactory to Squaremouth, that carrier is removed from the website and their products will no longer be sold.
