Cannot disable call forwarding on my Galaxy S7 Edge AT&T

[AC Question]

Went into phone settings and turned off "always forward".

Forward when busy
Forward when Answered
and Forward when unreachable
Cannot be turned off
If I turn them off they just come right back
Also the forward numbers is weird1-678-7569911-???. Of course If you call that number it does not exist in any form
When I make a call and there is no answer "call forwarded" appears.
Driving me nucking futs.
Thanks
