Does FC charge a fee? I was short with my payout, I was suppose to get over $80 & got $77.13... maybe I didn't read the fine print?? lol
There's no fee for payment on FC. Did part of your earnings expire? That happens after 180 days. If you look on the credit list on the My Account page, there is a status column all the way to the right. There it should say if the credit was denied or expired.
If denied, I suggest checking your email to see if you received a note about why the credit was denied. If no email, try looking on these forums to see if other members had the same credit reversed first. If none of those options are viable, submit a support ticket requesting the reason.
