I have been a member of Thumbtack for years. I have spent hundreds of dollars on leads. It's come to the point where they now charge $10, $20, $30 per lead and the 'customer' doesn't even respond. I believe they're farming out fake leads. Scam.
Then the refuse to give a refund because 'That is a valid charge and outside our Refunds policy since the lead is sent because it is matched with your preferences.'
What a smokescreen. This recent lead I asked for a refund, not only did the lead not respond, but the lead didn't even give me an option to quote on it.
Buyer beware
