We were on fumes coming home and pulled into last gas station for twenty two miles. We had waited a gas was 22 cents less a gallon. We had money in account, but bank declined card despite the fact funds were in account, and overdraft protection in place. We ran card three times, but declined all three times. We got text message five minutes later down the road, card was declined to protect back because they flagged it, despite having used gas station numerous times and only 35 miles from house. When I called and asked for supervisor I was told bank will flag sometimes to protect card holder. There was no reason to flag this card and it caused great hardship for us running out of gas on a school night and what a celebration turned onto a horrible night. Bank accepted no responsibility at all, we lost hours of time and used one of our aaa calls. This should not have happened.
