The first call I made resulted in the tech not finding my contract and making no further effort (I wasn't home at the time). I found the contract and called back. Had to pay the difference of $30 to get another pair of glasses. Twice I've used Asurion insurance and both times a hassle, but finally resolved. You have to pay the price difference.
