I cancelled my service with Osterman because they placed far too large a propane tank which rarely needed to be filled as a result, and then they charged me rent for the tank. I bought and filled my own tank, cancelled my service and asked Osterman to come and retrieve their tank. Besides picking up their tank, they DISCONNECTED MY propane tank, took the regulator and connecting hose, and capped the pipe. They did not inform me that they would do this, they did not return to me these parts which were at my house when I bought it but they switched out when I first became a customer. They simply left my house with no cooking fuel and REFUSED to come back to reconnect it.
