I will attest to the same issues many others have had. I talked to Jim Buffington who was very nice, in all honesty and he gave me a trial of 35 lead purchases, which i used about 20 or so. most ended up being outright fakes, although they claim they are all checked for fake issues. I'd say a fake phone # is a good marker. A few turned out to be real people, and admitted to joining sites that Qazzoo gets their leads from. One already had a realtor for several weeks, another was a doctor seething mad he was getting soooo many calls, yet Qazoo says only 4 get their leads. Another said he had no interest in buying a home.
One asian girl (sounded too young to buy anything) wanted to buy a house for investments, although none turned out to be anything more than a waste of time. Now, to be completely fair and objective, when i talked to jim, he said keep trying and if it doesn't work i'll give you a complete refund, and when the refunded 'leads' never appeared in my account and i wrote again, he simply said he'd refund my full purchase, $99, and close my account. We'll see if i get the refund. But I have a feeling they refund a lot of people!
