If you're referring to a mulligan, that's not available.
You can play an entire round in practice mode by simply changing it from Ranked to Practice when creating the game, or you can play individual holes by putting the cursor on the WGT Community dropdown up top, select Golf Courses, then the course and hole you'd like to practice. Each time you finish a hole, you have the option to play it again.
And no, you're not. I believe there's a support group somewhere.
