Tow Company Wants $4k For 3mile Tow And Refused Me A Copy Of Bill Unless I Pay.

I ended up having an accident thinking I could make it into work during bad weather recently and front end of my car ended up going into a ditch. I called emergency services for help and waited 2hrs in cold and dark no one showed so went home. Following day, I assumed car was still stuck and called a tow company for help in getting it. Just my luck first place I call confirms they already have my vehicle. Police did show up in middle of the night several hours later and called them for tow. I ask for rough estimate of how much I owe and let them know I plan on coming to get my car next day once roads are more clear. They informed me they are closed next day and have no clue how much it is at that time but come in when they open to discuss it. I already know my coverages on this car is not going cover it so I'm thinking at most I'm looking at maybe several hundred out of pocket and just hopeful I would be able to drive it 3miles back home and fix it. Soon as get to this shop owner comes out and tells me it's 4k, I ask for explanation of why so much for short distance and he says it took 2 trucks to remove it from the ditch and told me call my insurance and see if they will pay. He also didn't have a bill to show me at that point either. Went back later that day and brought the wife with me she immediately asked same guy I spoke to earlier to see a bill and went line by line asking for clarification of each fee and what it meant. None of his answers made any sense and he kept contradicting himself. Also Told her it actually wasn't 2 trucks but just 1 but we had to pay extra for flatbed charge since my car has 4wd. During all this back and forth he still was encouraging us to try get insurance to cover the full amount. He Even suggested we give him $2k and he would give car back and let him contact insurance and try get them to pay him the rest.I can see on the bill a bunch of pen marks where looks like wrote in an amount for several fees then marked it out and rewrote different amounts as well. We didn't feel comfortable handing over any $$ at that point so asked if we could get a copy and make some phone calls and get back to him. He refused a copy and said we only get a bill if we pay him 2k. My wife grabbed the bill snapped pics of it, handed it back and we left. I wish I would've listened to my wife and just stayed home that night but all of this seems fishy. How can I get my car for fair honest price? This can't be legal! I'm from VA should I consult a lawyer? Ge has to be breaking some laws here or have some type of insurance fraud going on. I found similar complaints against this place on BBB as well
