GasBuddy review: Premium membership agreement

Purchased 35 gallons gas with $0.20 per gallon discount per my GasBuddy Premium membership agreement for a total savings of $7.00, which I did not receive. I have not received any resolve after numerous customer support contacts by email and my requests to escalate have been refused by CADY / GasBuddy Support..
