IMessage contacts appear in OS X or iPhone when I have none

Hello.A month ago I was trying to import contacts from another account ... and testing vCard amount for hundreds of contacts on my Apple account. And then delete them all from my account. Now I enter contacts in iCloud and just leave me.Today I wanted to try iMessege to try it with mac and mine Iphone ... and box where you put your name I put some letters and have started dating contact names (which had removed some days ago), with the Iphone I see in the list that is coming out of contacts, I can check one and put "remove from recent" I have to do this for everyone? And I think I'll have hundreds to clear ... 😟I found a solution that has not worked for me:[I] first closes the application iMessage press Command / Shift / G keys to access the window / Go to introduce the following path / Library / messages / you've entered the directory where talks iMessages are stored now select all the files are in the directory and delete files will be similar to / chat.db - chat.db-SHM, etc Empty the Trash and re-open Messages i have if you have deleted the history [/ I]Regards
