Items restored to inactive account?

Over the last week or so I had 3 inactive accounts stripped, they used a "come back to Wow for a week" offer to activate them long enough to pilfer everything. I didn't notice the accounts were compromised until 4 days after they had begun using them, when they all got banned. I talked to a friendly CS person on the phone and everything was apparently restored, but I'm having a hard time finding out if it's complete because after the 3 day ban, my 7 free days are up.

I'm wondering if the in-game mail used to restore my items has a timer like normal mail? What about the Penquin and Core Hound pets? My accounts were inactive for a reason, no time to play currently... I'd hate to log in 2 months from now and have everything that was restored be missing. I'd equally dislike having to pay $30 to activate my other 2 accounts and loot the restored items. I'm only able to post this now because the hacker somehow got a 1 month referral reward on this account.
