When did the buyer first ask the question?

I mean, it is true that you can't answer PMs after 3 months, but you can still go to the buyer's profile and contact him or her from there.

A couple of times I got a refund and then the item arrived very late, once after 6 months, and I was unable to reply to the original PM because the thread had become inactive, but i could contact the seller from their main page.
