go to a good shop and have a new rear derailleur put on. it is possible since you have lost atleast two upper pulleys the threading is worn or stripped. since a common way to install a new rear derailleur (without a new chain) is to remove one of the pulleys, normally (atleast for me) the upper one. just politely ask them to ensure the bolt is tight and perhaps a dash of loctite. modern front derailleurs are very accurate devices and the days grabbing a used shimano lower pulley and making it work on the top are long gone.
