Lots of things I've never experienced before here.

First, Frontier usually starts with Zone 1. Rarely, they will board 1-3 rows. Not 1-5. They do this because the carry on compartments above row 1 are taken up with flight crew luggage. They make row 1 put them above row 3. So if you put row 1 luggage above you, as you claim, you wouldn't be able to do so because they'd point you to the next compartment (above row 2-3).

"She did this without my permission or knowledge"

So you didn't know you were moving to 25F? Did you sit down at any point?

If there were 30 people and you had 1A as you claim, they would have moved you to another Stretch seat. Not to 25F.

Either you had 25F and didn't know how to read the ticket (seen those issues on every third flight during boarding), or you're fudging something.
