blocked contact still able to send imessages
I have an iPhone 4S with software up to date (iOS 7.1.1), and recently blocked a contact, hoping to stop all text messages, calls, and (specifcally) iMessages. His contact info includes his number and his email address, so I was expecting it to block everything, but he was still able to iMessage me today. So I added him again to my block list, this time adding specifically just his email. Which means I have two entires for him on my block list, one that shows "name (home)" and "name (email address)". Will this work or do I need to change my apple ID? All the tutorials I've seen online are very basic and say that blocking someone through the message, phone and facetime also blocks iMessages, but it evidently didn't for me. And all the issues in the forums with blocking through iMessage are before iOS 7, so they're irrelevant to what I'm dealing with.
