Hi!
I have a hard time understanding what information you are looking for currently, sorry.
If you already made purchases and have the forms ready, you can (with Global Blue at least) proceed and have the refund issued to a credit card of you choice. (3rd-party: Husband, Spouse, Friend ...) (The only country this is not possible in is: Singapore.)
If you're traveling alone: Can you call a friend/family member to get their CC#? You could put that on the form, as you don't need to be the cardholder.
I'd still suggest you call Global Blue, or whichever service you decided to use, and ask them for help with this specific problem.
Hope this helps, and I'm sorry you lost your cards - it's a ****ty situation for sure. Best of luck and all the best for you!
Kind regards,
Oliver
