Don't get upset! She's found her error and is working on correcting it. I just got an email from her after sending her quite a few, only because I was continuing research in my notes to make sure we were talking about the same survey.
Here is what she sent me and please, see the mention of "kinder than most". It really pays to be kind to these people. They make mistakes like the rest of us.
Dear *****
Thank you for your email (kinder than most!)
I’ve identified the issue now, and I truly apologize.
Your completion code did not match any completion code on the list of the survey ‘Study on the Psychological Effects of Advertising Content' because there was an error in the MTurk instructions, where the instructions actually contained two links (to two different studies).
You chose the link which directed you to the wrong study called 'Detecting Fake News vs Real News' instead of the 'Study on the Psychological Effects of Advertising Content'. So when I checked the completion codes of the 'Study on the Psychological Effects of Advertising Content', yours understandably did not appear and I believed the HIT was not completed, so I rejected it.
I realize now you simply did the HIT but completing the wrong study/survey. I know this was my fault, due to having a wrong link presented to you.
I'm working to rectify this issue right now and approve your HIT as soon as possible so you get paid as soon as possible.
I'm a student conducting this research for my university degree thesis, and I'm learning from my mistakes. I hope you can forgive me.
Thank you,
Nicole
