Recover Hacked Snapchat Account

My Snapchat was taken over by someone else and I no longer have control of the username, password, or any linked recovery methods. I need an expert who knows the ins-and-outs of Snapchat’s support and appeal system to guide (or act on my behalf) through every step until full access is restored...
