Hostking

I have been trying to get this company to assist me with my disconnected emails to no avail. The email was set up by a third party and that person has all the information on security questions. I explained my situation and now I’m in a situation where I’m paying for a service that I’m locked out of. Numerous emails sent to Hostking still leave me without communication with my clients. Can someone help me, I’m losing business because I can’t reply to my clients or even bill them
