Samsung phone with PRELOADED Google items – “Google Play Services keeps stopping” popping up on phone. Have used help centre!

Tried all ways within Google Help Centre to correct this problem. Google Play Services now shows “Disabled” and “Force Stop” buttons now both greyed out and cannot rectify this latest problem. Also Google Play Store App will not open at all to show available app. I don’t want to lose any information from my Samsung phone, so I have loaded photos to computer and made a written list of my contacts.
Any help please to rectify the problems with Google on my phone.
