Answer on the way
I emailed the international concierge who came on my plane in EWR and made the reasonable offer.
He has emailed back and said he's sending the $500 voucher to me.
Will take some weeks to get here but trust it will make it.
Am I satisfied? Yes and no.
Remember $2800 paid ticket; half of trip seat doesn't work; insulting $50 voucher.
I will use the voucher and fly CO at least one more time internationally.
Will I continue to fly CO?
I don't know.
It's convienent but expensive and they have at least one good concierge.
High marks to you Mr Goodwin for knowing what "Customer Service" is all about.
