Panasonic — multi region dvd player

Address:

981/4 Ambirna Socorro, North Goa, Goa, 403501

I purchased through amazon a dvd player - i spoe to amazon and they told me it was delivered 2 dec 19; however, i was travelling, and just opened the package about 10 days ago - it does not play any dvds purchased in the u s or in the u k - it does however play vcds. I want to know what to do with this machine.
I need a replacement that does play all regions or a refund. Tired of people cheating me all the time. Certainly do not expect amazon and pnasonic to do this
