Republic Services review: Exorbitant prices/fees

I have been paying an ever-increasing amount for a 3-yard dumpster. $146 per month a little over 2 years ago has now evolved into $269 per month. My contract was out so I negotiated a new contract with them for a larger dumpster at a much lower price $136 per month for which I was happy. UNTIL I received my first billing: Old dumpster removal=$125, New dumpster delivery=$255, fuel/environmental fee=$220. The salesman conveniently "forgot" to inform me of these charges and their amounts. I asked the CS representative why they did not deliver the new dumpster and retrieve the old one in one trip, saving fuel, manpower, etc. She said that is not how they operate.
