BEWARE my experience with a Thumbtack referral has been a total nightmare. The "professional" they referred cost me $620. In losses commuting multiple illegal actions. He appears to be unstable and possibly dangerous. None of the claims made by their "professionals" in their profiles are verified by Thumbtack. Their definition of a "professional" to Thumbtack is anyone who wil pay their fees, no questions asked. When costumer service reps. Are contacted they have no authority to do anything other than offering patronizing empathy and offer to mediate between victim's and their victimizing "professional". No one will respond to my questions. No one at the company deputies my accusations or attempts to defend their clients obvious indisputable illegal actions. The " professional " stole my money and refuses to reimburse me. Considering their " professional " claimed to be a LLC and a trained mechanical engineer on his Thumbtack profile it was a surprise to learn he lives in a camping trailer at a local county park campground. The California secretary of state has no listing of the claimed LLC in their database. I'm certain this "professional" doesn't have the money to refund and may be violent if angered. I had a reasonable expectation that "hire with confidence" as Thumbtack promotes would be more than promotional empty lies.
