E Osterman Gas Service

Twice we've used Osterman for our propane tank. We only use gas for our kitchen stove, so we only need a fillup every 18 months or so. Both times we've called their office, we've been quoted a specific price, and when the gas delivery person arrives, they fill the tank and THEN present us with a bill for $.25 to $1.49 more *per gallon* than we were quoted over the phone. We're then told to call the home office if we have a complaint. The first time it happened, the difference was a few dollars, but the second time it happened the difference was over $50, and repeated calls to Osterman went ignored. The only positive--they did same-day delivery of gas, and the driver was nice.
