On an S5 Galaxy is there any way to stop AT&T Address Book?

A

AC Question

I Have tried every cure on this page and still unable to stop it.
Under App Manager there is no AT&T Address book App
Under Accounts the first Account is AT&T Address Book
When you tape it you get settings...Under settings the first option is Auto sync contacts
it is set to on and greyed out so you CANNOT turn it off. You can turn off master sync on the general phone menu....it goes away then you receive no emails on your accounts...when you turn it back on the AT&T Address book sync notification returns!
HELP!
