Wildwood's ambulance service is double-dipping us!

Wildwood - Wildwood's ambulance service is double-dipping us! I had to call for an ambulance, and not only did the ambulance come, a police car came, then Atlanticare's white SUV showed up too. A month later, I got a bill from Atlanticare and a separate bill from Wildwood Fire/Rescue. When I called Atlanticare, they told me their truck has the EMTs on it. So, Wildwood ambulances don't have any EMTs? Why are they coming to the scene? Next time, send one truck with trained EMTs and send me one bill. Isn't that the way it should be?
