The Mégane II Owners' Club

High all well my wife has just bought a Magane 2 and the Garage that had this has made a mess of trying to fix the door window, they removed the door card and lost the two screws holding the Handle and the two Long screws that fixed the door card and window track
Is there any way of getting hold of theses

try your friendly Renault dealer or a scrap yard ,But seen as its the garage that has caused the problem insist that they rectify
