App does not recognize correct password – Meta Business Suite Review

I manage a Facebook page for a business. I'm trying to set up my business page via my cell phone with the Facebook app and pages app. But neither will recognize the password I know to be correct because it is a password that I have confirmed is the one I sign into my desktop to(sat with my phone and desktop side-by-side and signed into the both simultaneously my desktop signed in my mobile did not.) I even tried to go into Safari and sign into Facebook using the credentials I know are correct as I have them written down and have confirmed they are the same as the ones are used on my desktop but still would not work. I have found several articles about this type of problem but no solution. There was an owner of this account previous to me and it was deleted but he is no longer employed by the party that hired me. I wonder if this part of the problem because when I send a password recovery through my computer I get all the information when I send a password request through the phone it is sent it to information I do not recognize. The phone number I don't recognize i have the option to send it to my email and select it but when the code comes Facebook reports an error and then nothing happens.I'm writing this review mainly because I cannot find a person to talk to about this issue and I need it solved. I understand app glitches the fact that I cannot find a phone number to talk to a live person about this is crazy. You all need to have a number to call to report issues so you know what to correct and to help your customers even if they're free customers. If could get this resolved I would be a paying customer because I would pay for advertising for my business. Please send me a private message to help me resolve this issue issue. Thank you.
