Facebook account restricted/banned after changing phone number and device - Need advice

​I am writing this because I am in a difficult situation and really need some advice. ​Today, while I was using Facebook, my account suddenly got restricted/banned while I was scrolling. I am very confused as to why this happened. A few days ago, I changed both my phone number and my device. I realize now that I made a mistake by not unlinking my old phone number from my account before doing so. ​I have already submitted my identification documents to Facebook to verify my identity, but I have not received any response from them yet. I am starting to panic because I work at the Ministry of Foreign Affairs of my country, and losing access to my Facebook account is causing me significant trouble. ​Does anyone know how to resolve this? Is there any way to contact a real person at Facebook support to fix this? Any help or guidance would be greatly appreciated
