exactly what the title says. I signed up for a phone call and completely forgot now I have negative points, how do I recover from it?

I didn't know what I was doing when I first signed up, so I ended up in the negatives too. You have to complete shops. Eventually you will get out of the negatives. Be careful about the ones that ask for a partner.

Positive/accepted shops raise your score, failed shops lower your score. If you do a few shops you'll be up in the positives... just take ones you know you can do that are quick and easy like some of the gas station ones where you need a photo of the front of the store and a photo of your receipt.
