Refund, absolutely. These car/motorcycle repair insurance policies are scams. I scored a deal on a new $38K Ford Edge for about $20K (long story), and feeling generous, told 'em to just add in the ($1600, I believe) after market service policy. Well, six and a half years later, at about 60K miles (policy is 7 yrs, 90K), the left rear bearing goes out. I've never had a bearing fail on a car or truck I've owned, and I've put a lot of miles on them (but have generally turned 'em over before 120K). In fact, I had taken the car to a Ford dealer just last fall, and they couldn't diagnose the problem (i.e. the noise I heard was tough to replicate). After a winter/spring tire switch, BOTH tires had that sound, like they were damaged due to improper balancing, but the spring set was nearly new. So, I thought "Oh oh, I was right, it's gotta be a bad bearing".
Short story long, after waiting SIX FREAKIN' WEEKS to get an appointment, the car by that time sounds like an 18 wheeler rumbling/roaring down the road, I finally get it into Ford, and they have to use a stethoscope to figure out which wheel has the problem. FOUR HOURS later, they come out and say "Yup, I guess you were right. We'll schedule you for the repair in about six weeks, 'cause we know you don't wanna wait all day for this", to which I said "Fix the damn thing, now, my day is already ruined, and it's a hazard to continue driving with this bad bearing."
Moral of the story: "Service Insurance" company informs me that they only pay for repairs if you call them in advance, and get their permission to fix the problem. The have enough policy hooks and exceptions, that they rarely pay out, and when/if they do, it's always less than the cost of the repair. If I hadn't ordered the immediate repair, I'd have had to either leave the car with Ford and rent a replacement, or park it until Ford could get authorization and schedule the repair "someday", and tell my wife to walk to work.
Nope, save your money, stuff it in a mattress or put it into other equipment.
