Trip Mate review: Will not reimburse us for trip missed due to company going bankrupt

We purchased Trip-Mate insurance at the same time as we booked our trip. We were to travel with Premier Tours Global. Before our trip was scheduled to go Premier Tours Global went out of business. According to Trip Mate's own rules under section IV, General Exclusions and Limitations - Benefits are not payable for any loss due to, arising or resulting from: (#17) "failure of any tour operator, Common Carrier, or other Program supplier, person or agency to provide the bargained-for Program arrangements for reasons other than Bankruptcy or Default.
Plan # 550A3 Cost $1974 each plus insurance for two of us. I would like to receive the $3948 that is due to us.
