I Was Hacked but Whatsapp doesn't want to help.

I was hacked and contacted Support. They told me to wait for 11 hours as it's security features. In that time my devices was removed, they changed my two-step verification email address & hacked a few of my clients. Instead of urgently helping me they caused my clients to get hacked and not only did I lose 2 clients, my potential clients no longer want to work with me, and my 5-star business rating is in jeopardy. Now it says I have to wait 6 days to reset. How many clients will they hit by then and how much more damage will I need to take.
