The shake & bank is deceiving.. I got the so called "$500" on one of my transactions but I never received the funds! This happened back in January and I contacted them about it after several business days after the 5 to 10 business days window and all they continue to do is say they are investigating the issue! I would understand if the problem is the transaction, but I have continued to receive the other rewards ( not the $500)from my transaction from the same account for other purchases made..
