I looked up this answer and have tried every available option. I tried to Block via iMessage - > Preferences -> Blocked and pressing the "+" but all it does is disappear whenever I click on the name. I tried it through FaceTime as well and it does the same thing. The number is blocked on my iPhone but will not block on my MacBook. It's updated (Mojave 10.14.4).

Hi kinaiaB,
Thanks for using Apple Support Communities. It sounds like you’re having trouble blocking a contact on Messages on your Mac. I’m happy to help. To start, I suggest making sure you’ve tried these steps:
Block texts in Messages on Mac - Apple Support
Should that still not help, I suggest signing out of, and then back into Messages. You can do so by opening Messages and then clicking Messages in the Menu Bar. From there go to Preferences > Sign Out.
Let me know if that helps.
Take care.
MacBook Air won't allow me to block a contact
