I've seen some similar situations online where Steam support made an exception and reactivated the reservation after a support request. Maybe worth trying.

Email Valve customer service and let them know what happened, it's possible they may be willing to help out.

A real life thots and prayers situation. 🙏

My heart actually does go out to you that shit sucks massively.

Hopefully you aren't clinging to the remains of a previous controller as you wait.

Contact Valve support, be nice, and they will be nice too :)

thanks gang, I appreciate the sentiments and advice; and shall do just that.

Also, talk about a good problem to have, being on an amazing holiday in Europe 🙃
