Bests & Worsts Reviews from Amazon

I made the mistake of buying the protection plan, seemed like a good idea until I tried to register my product. I keep getting reply emails saying"Unfortunately, we were unable to process the receipt you recently submitted" . After the fourth try (following all directions), I decided to register on their site, that ended with a we are sorry but the registration could not be completed error. I have wasted over 90 minutes with this very poor company.
