I signed up for a couple of offers on July 18 and I have yet to receive my rewards. I didn't know who to contact about this so I am posting here. I used the same email that I have registered here for both as I can verify with the confirmation emails from the offers that were sent to me right after registering.
If I am somehow ineligible to receive those rewards, then I would suggest that a message be sent to those persons who sign up for an offer but are denied the CPs.
