Hi I need help! I have several business pages, recently I opened a new physical business venture and am taking over a pre established art business. When it came time to merge our pages. (Both with very similar content, just different title and address)*It kept sending me to a page to verify my identity , by sending varification number to my phone number. I tried to send it multiple times, I never recieved a verification code, and now I'm getting a message saying that I'm not using the button for the verification code the right way and my profile and both pages I was working on seem to have erased out of existence. My FB account, and businesses I was trying to merge are erased. None of my friends can access my account, I dont even appear. My other business pages are just floating around without an admin, the accounts that I shared admin access too has my image greyed out as an admin in the settings page. I'm literally dying over here, at this point ive lost my combination of *k worth of marketing potential, and basically my businesses main point of contact. Im freaking out, I dont even know what's going on. Please help, I use this avenue for a main source of income.
