Why am I not receiving the verification code on my phone number even though it's the number shown on my Facebook account? The code is being sent to a different number that isn't mine, and that number doesn't appear in my contact information.

My Facebook account was hacked, but I was able to recover it. Now I'm trying to secure my account by enabling two-factor authentication, but I can't set it up because it requires a verification code. The problem is that the code is being sent via WhatsApp/text message to a number that isn't mine.

​

Can someone help me? I don't know how my account got hacked because I never logged into suspicious links, and I haven't been actively using my account. I've already added two email addresses and my phone number, but the real problem is that I can't receive codes on the number listed in my contact information. Instead, Facebook keeps sending the code to a different number that doesn't belong to me.
