<human>: Can you condense the text into a few key points?

Hi Reddit,  

Made this account just for this question.  I bought a new Mazda 5 in 2012 - put $2000 down on a standard 5-year loan to pay it off.  But I have been extremely delinquent in my payments - after paying for the first few months I basically stopped paying because I couldn't make ends meet.  First the bank and then collection agencies started calling - after a year I had the money again and contacted the bank and got current.  However, I haven't made another payment since then.  Mostly, it was because I didn't have the money, but then it became because I didn't know what I owed.  I've had collection agencies call, and people (and lawyers) who say they're from the bank - I've been hiding from their calls.  I'd like to get current on this and at the moment I could pay it off entirely.  My question is, who should I call back to get this part of my financial life back on track?  A collection agency?  The bank?  A lawyer?  

Thanks for any insights you can provide!
<bot>: I bought a car that I haven't made a payment on in years.  Now that I can pay it off, who should I contact to do so?
