Is there any way to speed up an App Review?

Hey, we use Facebook Login for our website. Facebook spotted an issue which got fixed but I believe what has happened is that we forgot to get back to Facebook and ask them to re-test it and now they have just gone and disabled our account.
Is there any way to speed up the process of re-enabling the account? Starting to feel like enabling facebook login at all was a mistake if they just go and turn it off without any direct way to get it re-enabled for us, users not being able to access our product is quite problematic.
