I have a deleted contact still coming up when I type their name into messages
I deleted two contacts from my contact list. I then went into my iMessages and deleted all conversations with these two contacts. I also did this on my iPad and iMac. I also went into the contact list in iCloud and they do not show up there.  Gone, all gone!  To double check that I could no longer see them I started typing in the name of one of them in a New Message on my iPhone and there he was. I typed his name in New Messages on my iMac, he didn't come up but when I typed in his phone number his name and number came up for me to message him. There had once been a joint conversation with the two deleted contacts and that is what shows up on my iPhone when I type in his name. I can block them individually, but I can't delete them on my iPhone however it looks like I can't do it either on my iMac.  How can I delete these people for good off all my devices? Â
