Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Rewards New York

I have a BP credit card that advertises rewards for either -, -, or - cents per gallon depending on what you purchase. I have no issues with credit when I purchase gas at a BP station, I get credit at - as advertised. The issue is when I purchase other items, they either reimburse at the wrong rate or not at all. They claim a railroad ticket or a taxi is not transportation so not reimbursed at the - cent rate. Also, they make it extremely difficult to match up a purchase to what was rewarded back to the customer. Purchase history is on one site and reward history on another site and of cousre there are delays in reporting. Then customer service claims they have no view into rewards, which of course is not true, if I can see it they can see it.
