AmeriGas Propane review: Bill!!!

Im being charged for a guy to come out and remove a lock on the gas, which should never have been put on in the first place, only reason, was because I was never called or notified that gas was on the way, which I told them atleast 5 times in the 9 days I was without gas and since I wasnt home, you locked it! They were well aware there was not a leak, just had to lock since I wasnt home! I had to call and request lock off so I could use gas! This is all after going without gas for 9 days, my entire home is gas and I have small kids in the home and pets! Im being charged $500 for something I should not be! I have also written a formal complaint to the agriculture/ consumer protection as well! I feel im being billed as a scam! Even the guy who came to unlock was well aware of the issue and said other clients were suggesting the same!
