Citibank Shell Master Card 5% cash back NO MORE

I have the Shell MasterCard® from Citi® Cards that used to offer 5% cash back on purchase spend on gas at Shell gas station. It's been working good until about a month or so ago they changed the terms and conditions bla bla bla... you now have to spend up to $500 a month to begin getting some money back. No thank you!

And when I logged on to the account at https://www.accountonline.com/cards/svc/Login.do?siteId=SHELLCREDITCARD, there is another message:
Please Note: Due to upcoming system changes, the AutoPay feature will not be available after July 22, 2011. After July 22, you must pay your bill each month online, by mail, through your bank or using a bill payment service. For more information, please contact Customer Service.

No auto-pay? Inconvenient you customers and hope to collect more late payment fee?

I called their Account Assistance at 1-866-743-5562 24/7 and canceled my card.
