Get my car out of Repo

Woke up this morning to find that my car was gone. Found out my bank had repossessed it over me being behind by $20. Unfortunately since it has been reposted I now have to pay almost $900 in late fees and two fees to get it out. Also only have 3 days to come up with it or else it goes to auction. I need my car to go to work, so I can make money to pay bills. Please help, I dont know what else to do.
