When a traveler’s claim is denied, this can lead to Global Alert complaints. The denial could be the result of insufficient proof of loss, the traveler waited too long to report the claim or the traveler’s loss is not covered per the policy language.

Unless the carrier provides a solution satisfactory to Squaremouth, that carrier will be removed from the website and their products no longer sold.
