First, a receipt sat unprocessed for over a week. When I asked, I was told that regular unleaded gas is not included in the offer at that station - even though it is again currently, was before, was then, was after, was unlocked. They said it couldn't be processed, even though they acknowledged that I'd unlocked it, and I provided proof that it was the correct product. So they decided to stop responding. Absolutely textbook bait and switch.
