Don't use Craigslist for paid job postings. If anything happens, the customer service is non-existent. They pretty much stole $75 from me because the site said the credit card I was trying to pay with was invalid. I re-entered the information thinking I had not gotten the billing address right and even though it came up as invalid, I was charged each time anyways!
Update: After a few days, Craiglist responded with a message saying the payments were pending and if there was only one ad posted I would only be charged once. They said the pending payments would be cancelled within 10 days. We shall see... I changed this review to one star since it was not confirmed that they stole my money, however, if the payments are not cancelled, it will be changed back to one star.
