Facebook review: Account disabled

My account was locked on 4/1/26. I have been constantly trying to get back on but facebook has not responded. On 4/1 I received a security alert that my account MAY HAVE been hacked. It came from a phone number in the UK. I was very suspicious but sure enough I could not get into my account.
Facebook asked me to prove my identity with a credit card. The card they wanted me to use expired long ago and no longer around. Facebook tried to send a code to a phone number now disconnected. I hve told them many times what the correct number is but they don't respond. I tried their help page. It's also unavailable.
What's even more disturbing is that before this happened, I was harassed on Facebook by an obsessed stalker. I never responded to her. I blocked her and sent her posts to FB. They told me that she had violated community standards. I hoped that was the end of it. Maybe it wasn't. I would not put it past her to try to get into my account. She is clearly deeply disturbed.
There are people on Facebook trying to get hold of me. It's been nearly a month and I miss my friends so much!
