The hammer dropped - rejection #4.
UWCartLab on a $3.50 hit says "survey not completed. Wrong survey code". I know I'm not the only one here on MTC that reported only being able to part of the survey because of some tech problem.
I contacted them right away explaining why I used my worker ID and where in the survey the problem was. They never replied back and a week later (tonight) dropped the rejection on me.
I have contacted them again trying to make my point that the rejection reasons were for things out of my control and said I would retake it for the $3.50 when the tech issues are fixed.
