The article below is the answer from blizzard, if your account also get hacked you can try it. But I’m not sure they can really figure it out.

First, please rest assured that in almost every case, the full extent of any damage inflicted, including battle.net merges, item loss or the theft of gold can usually be undone. We have quite a comprehensive system in place to ensure that where possible, everything is returned as it was when you last logged in.

To begin the process of recovering your account, it's best to start by contacting our Account Administration team via the web form on our support site. This form allows you to attach some identifying information to help our support staff verify that it's really you, the account owner contacting us, and from there they can do their best to assist you.

As well as that, you may also find that calling our Account & Billing team over the phone helps to speed up the process, but their involvement is often limited based on the circumstances surrounding what happened to your account, and so they may not be able to help further.

Finally, once your account has been returned to you, contact a Game Master in-game through the ticket system if your items haven't yet been reimbursed, and we'll finalise the investigation by returning everything that we can.
