WotLK Deleted items

[Kisstheleet]

As the title says, it's the first time I've logged in around 4-5months on my DK on Icecrown, Kisstheleet, and I find out tat all the items that I've had, including two herald tank and dps sets and an almost full bis frost dw dps set are missing/deleted, and also that I've got no gold. Nobody ever had access to my account or password, and I wouldn't do that on purpose lol. What is it that I can do so that I can recover all my years of ingame worth items?
With regards,
Kiss.

nothing. item/gold don't disappear on their own.

I've checked on the website as well, nthe only IP the account has been logged from is from the one I am using, so that gets out of the way, definitely. Nobody ever requested a password change apart from me, 7months ago. Plus, the last time I logged, everything was in place lol
