Can't use Steam Marketplace until July the 21st... [SOLVED, will leave here as a warning]

I was in the middle of a trade, seller asked for keys, I added funds to my wallet using Paypal, as I had recently cleared my cookies/etc. and I wanted it to be faster than looking for the credit card number.

Steam tells me I can't use the market until they verify the funds. Screenshot of what it says, in Spanish.

Fuck my life, in the middle of the summer sales.

Is there anything I can do to speed up the process?

Can I add funds again with the verified credit card to "unlock" the market again?

EDIT: Thanks for the replies, and thanks for the Steam chat advice, I guess I'll have to wait.
