To clarify for everyone, this looks like a 3 one-way reservation, with the last 2 sectors operated by AC.
The extra baggage charge for transborder flight should be $50, and the international flight should be $100. Unless there is a 3rd bag or if the bag is overweight/oversized, there's no reason for the computer to charge $200.
I would first request a refund with AC.
