Instant Checkmate Wrong information , Internet

I purchased this service and could not find information on three different people even though they have extensive records. I looked myself up and found wrong information on me including my birthdate. I called and asked about it and the response was that they get all of their information from public record. I've recently had a complete federal and state background check on myself through the police and a state agency using my fingerprints. There wasn't any mistakes on my date of birth or any other records. When I asked for my money back less than an hour later, they would only refund 50% of my money, saying that I made too many searches for a full refund. Even though the information that they advertise to be in those searches were not.  Bad business!
