Called ahead to make sure they charge per gallon. Once I drove over they said they would not. Only charge flat fee to fill tanks even though they dont need completely filled. Wanted to charge nearly $4 per gallon. Propane cost currently is only $1.34 per gallon. Terrible customer service. I will never use this MFA. Lady on phone and in office was nice, guy in other office didnt even get up from his chair, just poked head out of door and said they are unwilling to charge per gallon.
