Possible Scam for free data

I finished this study in about 20-25 minutes and then it led me to another survey in survey monkey instead of a redirect back to Prolific. I was confused and surprised, but I saw it to the end anyway. I completed that other survey and then was led to a "Thank you for taking the survey, click here to take another". No completion code or redirect link provided...I returned the study and told them my complaint. I feel like I just got scammed out of my time and data...bummer
