MFC wrongfully repossessed

I bought a Hyundai Veneu in September 2020 my contract state that my payment will be made by the 29th of each month a year later I bought a NP200 and that contract state that each payment will go off on the 1st of each month MFC came and took my Veneu by force and broke the reareview mirror in the process and never explain the right that I have on the Veneu when I call the lady Bronwin about my Veneu to resolve the issue but with no luck at all she had no patience with me at all. My Hyundai Veneu was signed and submitted before the NP200 and they took the payment off the NP200 1st what was wrong off them because off the contract that was 1st submitted
