I had the misfortune of acquiring Covid-19 while traveling. This resulted in trip interruption because of necessary isolation. I had purchased IMG travel interruption insurance and felt I was covered adequately. It turns out that this was not the case. I wish I had read the reviews from other travelers with IMG claims experience. The IMG strategy is to harass their policyholders by requesting information multiple times. After you comply with one request, they will come up with new and increasingly difficult to obtain documentation and also usually ask for information already supplied. After numerous cycles they will still deny. In the end my claim and appeal were denied because I could not provide documentation that I received a "mandatory quarantine order from the local government". Yes, you read correctly - IMG requires the local government to issue a mandatory quarantine order or benefits will be denied.
Don't waste your money and time on a policy from IMG.
UPDATE:
I ended up contacting the broker (SquareMouth). They assigned my case to their "Zero Complaint Team". The representative asked me to submit my documentation to them. They updated me weekly and, within a month, my claim was paid nearly in full. I would definitely recommend SquareMouth (they offer policies from many insurers) but will not be purchasing an IMG policy again.
