Amen to this.
Exactly the same thing happened with my Arcteryx jacket. Boils my piss how companies preach sustainability and environmental responsibility but don't follow through with actions.
In a similar vein, a screw came loose and dropped off our pram / pushchair recently. The manufacturer declined to supply a spare screw but offered to sell me a new chassis for over £300. A few choice comments on their social media and funnily enough they sent me a spare screw free of charge.
