Disappointed

I kept receiving these messages from Toyota: Toyota is concerned that you have not replaced your Corolla/RunX RECALLED passenger airbag yet. We URGENTLY require you to fit the safer airbag. Please call your dealer to book a free airbag replacement.

I called the dealer last year and an appointment was scheduled, they promised to come and do the replacement at home but they never came. When I call their HQ to follow up I get feedback that someone will call me back but that never happens. Toyota are you going to replace the airbag or what?
