Java Netbeans 8.2 Download

Hi all, my I Phone 11 froze last week and is sometimes turning off/on. It froze turned off came back on and had kicked me out of all my accounts online, Apple ID and facebook etc. As it uses face ID i never needed to remember my password for facebook and whjilst I have eventually managed to get my Apple login sorted, my facebook is still not able to be logged in. Its registered at an old fsmail.net email and I never included my Mobile so thats the easy way of resetting the password gone! Can anyone suggest a fix I have emailed [email protected] and also [email protected] and I'm hoping I will be able to recover my Facebook. Im in the UK but just wondered if anyone had a similar issue with the I Phone 11 too? TIA :)
