I was bitten by a dog and I was told by the police...

I was bitten by a dog and I was told by the police that these guys were suppose to contact me with the information in the dog that bit me see if I needed shots.
They called me and said they recomended I get rabbies shots for the dog bit cause they do not have any information on it.
I called them back because I was lead to believe they were suppose to give me information for the billing, so I dont have to pay for the dog bite treatment that they owners would cover it.
They have no information about the dog, they cant help me with rabbies shots, they cant give me any information or help at all about billing etc.
My question is, why is there a health department if they dont do anything helpful in the first place?
They have not done anything except tell me to get expensive shots and that they cant help with anything else. If I could give them zero stars I would.
