Great.1. I read it in their mail or email response... Worst case send a photograph of your had written letter to your friend as back up.. should work
2. You decide now.. For me I chose proxy.. later I asked my friend not to go due to covid... Them requested them to change to collect it by UPS
I will first choose the proxy, but I will change it to pick-up in case of any issues like yours. Is it easy to request them to change the mode from proxy to courier pickup? How did you do that? by contact them via email?
