It's not just the mouthwash brainjuicer. I did one well over an hour ago and it was about an ad idea for a well known hardware store. I took my time, completed the survey, was thanked, was asked to give my opinion and suggestions about the survey. Then it went to a page to type in a code to get credit. I typed in the code and it went to the TERMINATED page. I know it is not going to credit because I can try to get another DS and that never happens when you successfully complete one. This is very frustrating. I did another brain juicer last week for one of the other survey companies. I completed that one and it never credited either!
