@ha11 and @cvkemp: FWIW, I have had a couple of tickets with Oticon’s repair lab go to 3 weeks without my aids being returned, however, I think 7 weeks suggests a problem other than the typical Cover excuse. Have you considered phoning Oticon or emailing them directly? They don’t like that, because - as Chuck has pointed out in the past: we are not the client; the audiologist is! - but my experience has been that the end-user contact gets the ball rolling again.
