They were suppose to autofill my tank. But I ran out. The lady is giving us grief saying they did not have a credit card on file. His house is on the same account, and his house is always autofilled using the credit card on file. She told us, they do not hold credit cards on file. But this is the card they use to fill the tank on his house. Not very happy. He is a dr. and he never has problems with his. This is very distressing.
