Facebook won’t let me log in and have banned my account

Yesterday I tried to log into Facebook and was met with the following message:

You can’t use Facebook at the moment, we’re reviewing your submission. We’re always looking out for the security of our community , so until then you won’t be able to use Facebook.

My whole business revolves around Facebook, linked to my personal account. I haven’t breached any guidelines. Does any one know how long it could take to get back online?

Thanks
