Lost bag in taxi from Camden St to swords & malahide

I left my bag in a taxi on Saturday 4th April @4am. I was taking it to swords & malahide with my boyfriend. I got out to get money at a pass machine on Camden street and my boyfriend followed and the taxi drove off, he must have thought we had changed our minds. Can it please be returned as I had a recorder in it which is very important to me. It is quite a large blue fabric bag with makeup, a top, brushes, recorder and notebook.
