Forget cloud ID pass and locked,email locked also

The phone is on the activation lock screen ? Have you tried contacting Support and seeing if they can reset its password : Contact Apple for help with Apple ID account security ?

Or, and if you were the original purchaser of the phone (i.e. it wasn’t bought used), you could try going to an Apple Store (make a Genius Bar appointment if you do) or try contacting iTunes Support online (https://www.apple.com/emea/support/itunes/contact.html) and see if they can remove the phone from the account - they are likely to want to see proof of ownership before they might help e.g. original receipt with the serial number on it
