Our offerwall partners require us to hold crediting on certain higher value offers due to instances of past fraud and non payment. The offerwall partner will review your offer completion to ensure there are no issues before we can reward those points to your account.
On https://www.prizerebel.com/offers_completed.php you are able to see the offer that is pending and points will be added to your balance 30 days after review assuming there are no issues. The 30 day wait period starts the day after your offer completion date.
