Got hacked and secure link FB sends is invalid

so account got hacked, all contact info got changed and the D bag tried spending my paypal, but i stopped it, thankfully. FB send me an email to secure the account, multiple times, but the link they sent is invalid. if i try to login using email, number or name, it won’t work because all that info got changed. Zuck and Co suck, and i hardly use the platform anymore, but i want my account back. anyone have a tip?
i find it totally absurd that they can have so much info about users, especially payment info, but not have a customer service line or chat. mind boggling.
