AmeriGas Propane review: Help

I've been a customer for over 15 years! I've paid 150 to rent a tank every year. I've filled my tank as my one fireplace will burn. i called to order gas today. 4.50 a gallon with 2 other local companies called one at 2.85 and one at 3.05 respectively. Also I was told I had to pay a 140.00 for a serviceman to check for a leak, I still have 30 percent. So no leak, I called last year and was told I did not have a low enough to make a fill so I'm screwed either way. Tried to talk to someone who spoke English. Called p ladner at corporate to see if I could get someone that I could understand or better yet they could understand me. No luck. I asked one of the broken English people what I need to do to just stop the tank lease, I am told I have to pay a 100.00 disconnect fee plus a 299.00 removal fee for something I don't use except for the fireplace. What kind of business is this. So the only way I can get out of it is to sell my house is what one of them said. RIDICULOUS SO UNTIL I DIE I HAVE TO PAY 400.00 to remove it or 150.00 a year for something I don't use... Buyer beware these people are SCAM ART.
