Facebook complaint: Account locked without reason

Hi,
My name is Cristian Remy Andreiu, a few days ago i received a email stating there was suspicious activity on my account and that it got locked. Its very weird as at the time im with my girlfriend meaning im not opening fb at all…. now i changed my password right after hearing this, tried to click the link… wich is broken as it straight up locked my account, removed my phonenumber and gmail options and made me unable to retrieve it by removing my known devices. Here comes the weird part i did not do anything and im just trying to get back hold of my account. I have people on there that sadly passed away and i can never retrieve.
Ive tried every possible option to retrieve my account and cant even fill out your forms as it tells me straight up to log my account (wich i can but its locked and i cant undo that now). I dont know if someone is reporting my account or if it simply it got hacked. I do know i never posted and will not post anything against your legal terms. (Especially before the lock i just signed for a competition from a local shop and tried finding a home using your marketplace and page options.)

I have been using the account for many years and dont even wanna try risking losing it as i stated up above: i have people on my friendlist there i can never retrieve… also its the only way i can contact my family in different countries.

Now im trying to solve this peacefully hence i send this mail.

Please help as i’ve tried every other option…

Kind Regards,

Cristian Remy Andreiu
