icloud refuses to recognise my ID and password on MacBook, iPad and iPhone
Since updating iOS and OS X iCloud, Facetime and iStore cannot be accessed. They do not recognise my password. I did not forget it. I have reset it three times and received confirmation emails. I have restarted all three devices many times and reset the iPhone and iPad. Apple Support is useless and not accessible at any time I can speak to them.
MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.3)
