You can request the window is extended, not guaranteed to happen though. Offering to reship only if dispute is cancelled is a sure fire way to lose your coin, but if you're a new user I don't blame DD TBH.
There is no proof of shipping on 1st class post so you already know that's not happening. Reputation based settlement is probably best for all.
