From my experience, which may not apply to you, when you purchased the Allianz Travel Insurance product, there was a review period when you could cancel the insurance without any penalty. After the free review period, then you probably had no legal right to cancel the insurance and receive a refund of what you paid as premium.

If you can find a copy of the policy - which almost certainly was sent to you by email or hard copy in mail, it will have information about canceling the policy and the possibility of receiving some form of refund of premium.

In any event, you should contact them to ask the question. If you cannot get through on the 800 number, then send them an email using the form that is on their "Contact Us" page.

My experience with Allianz has been very positive - others have had negative perceptions - it never hurts to ask.

Good luck.
