I got this a few days ago
"We appreciate the opportunity to assist you.
I have confirmed that 45 days have passed from the purchase date. Since the reward for this order is rather large, it is our policy to investigate with the merchant to find out why it was not credited and attempt to obtain payment for the order in order to pass it back to you. Therefore, I am sending this order to be investigated immediately. Because a third party (The Motley Fool) will now be involved, we ask that you please allow 4-8 weeks for a definite resolution. However, we hope to have this issue resolved much sooner than that.
A representative will follow up with you periodically to let you know the status of your case. "
