On all these threads I am always amazed by people who feel the need to argue AAs position to the OP.
OP, you can assert whatever you want.
AA has already ignored you. Thats done. You can keep repeating yourself with different email boxes, but I wouldnt.
Next step is a demand letter, for YOUR point of view. Claim what you want. "here is the total or I take the next step'. Paper, Certified.
Then a small claim case.
IMO they will settle before the case date.
(If you want to read nonsense, read the thread on "help me sue AA"....)
Oh, rest assured that YOU care much more about the relationship with AA than AA cares about their relationship with you.
