Re : Exxon/Mobil gas credit card - credit price vs. cash price. 
Previously, when I have used our business gas card my regular Mobil station ( s ) has applied the lower, cash price, to the gas card transaction. On XXXX/XXXX/15, while at an unfamiliar Mobil station, I was charged the higher, credit price, for my gas card transaction. 
This seems to be, at some level, a bit of consumer information fraud. The lack of consistency is XXXX thing, the failure to disclose to the consumer is yet the large issue. The consumer has no way of knowing the amount he/she will be charged ( cash or credit price ) when using their Exxon/Mobil gas credit card until starting the actual transaction. 

I 'm surprised this has not become a class-action lawsuit yet. 
Thank you for investigating.
