Has anyone received a response from customer service for things like completed surveys that you didn't get credit for? I submitted a request for one 2 weeks ago and have heard nothing, and submitted another one today after completing a long survey, getting the "you have completed" and "thanks for completing" messages - then when the "You have been credited X dollars" all I got was a 404 error screen. It seems to happen a lot and normally I just shrug it off - but not after spending 30 minutes.
