The used car dealership I bought my car from is trying to say I haven''t made any payments. I have paid almost $2000, but didn''t keep my receipts

I am assuming that you paid in cash or in some other form where a receipt from the dealer would be your only evidence of payment. That means that if they decide to sue you for the amount due, then it would be your word/evidence against theirs.  My concern is that your contract with the dealer or its finance company probably gives them the right to repossess the car so that you don't ever see the inside of a courtroom unless they then decide to sue you for the balance of the payments.  Because of their right to repo, you need to work with them to resolve this matter. What other evidence of payment might you have? Did you pay with a money order or some form of payment other than cash so that you can go to the provider of the instrument for evidence of them and their date even if not the recipient? Maybe they would be persuaded to look further if you could show them withdrawal slips from your bank in such amounts? It's best if you can work this out with them sooner rather than later to avoid a repossession.  If you can't do so quickly, I suggest that you reach out to the Governor's Office of Consumer Protection to get some help.
