This is a solvable problem, and you've come to the right place.  We can help. 

The first thing for you to do is often the hardest:  WAIT.  The process that distributes the points can take up to 15 minutes from the time the quest is completed to do it's magic.  

Next... have you waited?  I mean it, 15 full minutes.... assuming that you have done that, the next step is to fill out our convenient, nifty little form and tell us you're missing the points.  

Then, guess what?  Wait. A community team member will review the data that you send us and will (assuming there was an error) credit you with the points soon.  Please allow us up to five business days to process these (though we try to be much faster).  If we need further information, we'll email you, so please keep an eye on your email.
