Blocking feature not working

Hey carley115,

We'd recommend reviewing this article for information on blocking contacts in Messages: Block phone numbers, contacts, and emails on your iPhone or iPad - Apple Support

"Block a phone number, contact, or email

There are a few ways that you can block phone numbers, contacts, and emails.

Phone

From the Phone app, tap Recents, then tap the Info button  next to the phone number or contact that you want to block. Scroll down, then tap Block this Caller.

FaceTime

From the FaceTime app, tap the Info button  next to the phone number, contact, or email address that you want to block. Scroll down, then tap Block this Caller.

Messages

From the Messages app, open the conversation, tap the contact at the top of the conversation. Tap the info  button, scroll down, then tap Block this Caller.

Mail

From the Mail app, open the email that has the contact that you want to block, then tap the contact at the top. Tap Block this Contact.

You can also add a phone number or email address directly to your Blocked Contacts list in the Settings app.

1. Add the number or email address that you want to block to your Contacts. 
2. For phone numbers, go to Settings > Phone > Blocked Contacts > Add New. For email addresses, go to Settings > Mail > Blocked > Add New.
3. Select the contact that you want to block. 

When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked. When you block an email address from Mail, it goes to the trash folder. Email blocking works across all your Apple devices.
