My contacts are on my phone and I can choose them from the contact icon. I can not choose them to make a phone call or send a message. Incoming phone calls and messages do not display the contact name, I have tuned off contacts in iCloud and then back on but it did not fix the problem.
I did something in Facebook that was sending out friend requests to everybody. On trying to stop that I lost my contacts being attached to my phone calls and messages

Maybe you had Facebook contacts on and turned it off when trying to solve the other issue.
Check on Settings > Facebook to see if contacts are on.
In order to be able to call and that incoming calls are identified your contacts need to have the phone listed. It also may need to be written in a specific format (+country code (area code) number, for instance).
