Fiverr and Youdata

Fiverr, it may work for some people but not for me, I got an inquiry about a research gig i posted with a pdf. The customer asked and I did and he asked some questions and requests and he was happy and I never got paid and it happened twice. I waited 30 days and contacted customer service and got nothing. Youdata, get paid to watch ads its nickel and dimes, to signup they ask for your cell phone number. They dont have a lot of ads, and if you carrier is not listed then you cant sign up.
