I used the website's (BE) feature to request credit and entered all my ticket numbers (which were already showing anyway, with zero base points). I did this about 2-3 days ago. I just logged in and they had posted my points. Looked like a manual adjustment posted by customer service. No email, no explanation, nothing. They just posted the points and they were correct. I'd pursue this route as it seems to work (and it's not the first time I have to go chase the points this way).
