In my case all the stations that had a cut off it WAS the gas station limiting their losses. The first time it happened I immediately called my bank and it was not my credit card.
During the first time I hit the road full time I quickly learned it is prudent to tell you bank BEFORE you embark on extensive RV traveling! :W
The first time I crossed state lines within a day buying gas, rv supplies, food all that activity sent up red flags to my bank and they shut down my card. And then once again when I encountered the limit on the pumps when gas was so high I needed 3 times running the card to fill the MH!
The second time was 'activating' one of my cards on the road 4 states away from home and on the same day hitting the grocery store, RV supplies, gas, and 2 fast food stores! I called to tell them it was me and the bank said boy you must have been really hungry! :B
