Facebook suspended my account with no reason why

last week I set up a Facebook account using my email address and added some photos to an album and a business page to try to get some work during the lockdown. I tried to log into my account a couple of days later only to be told my account had been disabled because of an issue with Community Standards, there was no warning which would have enabled me to resolve whatever the issue was.

I have now received the following response with no real explanation.
"You can't use Facebook because your account, or activity on it, didn't follow our Community Standards. We have already reviewed this decision and it can't be reversed.”

I would like to know how I failed to follow Community Standards, the account was in my name, the photos were my own work and I had not actually posted anything.

I cannot find any way to contact Facebook to find out what the exact issue is? I’ve looked at the Community Standards page but still have no idea what the problem is.

Does anyone know of an email address for Facebook that I could contact about this or does anyone have any suggestions as to what the issue might have been (I realise this may be difficult without access to the actual account)

Thanks
