Need help i lost my eq

I have come against an issue. Last time I was playing WoW which was like a one year ago I left my warrior with a gear of 5.8k GS. Three days ago I decided to get back to WoW and logged on my warrior but what I saw there is that I don't have a one single item on my warrior. I just lost my whole equipment. Can you give it back to me from your database or something ? Thanks in advance,

You can reclaim items you have bought for coins, otherwise they are gone for good.
You should make a proper ticket, this post will unlikely get you some result.
Check your login history, trade history, make sure you have 2FA, etc, because looks like someone cleaned out your account.
