I booked a vacation for my family and had to cancel. I paid for the insurance because of the covid stuff. They have not refunded over $6500. Wont answer my calls and just give me the run around. It's been almost a month and I'm looking it getting a lawyer. Do NOT book anything with them. They kept changing my flights charging me more money. Just a bad experience all around. STAY AWAY
