I just completed a LONG 5 hour research study in person for Addison Research in NYC for a User Interview study. I signed up for the study on the User Interview website. We were told to expect a $200 payment via paypal after the study yesterday. I even called them on the phone yesterday evening to confirm they had the correct email for payment. (Good thing I did because they were actually missing one letter in my email address). Still no payment today. I am very angry. I gave them 5 HOURS of my time. I hope that it is just because it's the weekend and to expect it Monday.
Has anyone else done a study with Addison or User Interview before? I did one alcohol taste testing for them last month too, but they paid onsite immediately afterwards. Should I be worried?
