I received an e-mail overnight from SQ stating that as a courtesy I would be receiving a refund of the original taxes paid and balance of miles as stated in my original cancellation call. I assume those will be subject to the original expiration date, which I feel should be extended ~2 months due the misunderstanding and wait I've gone through waiting for them to be re-deposited. Once they actually hit my account, I'll push for some kind of concession to that effect, although I feel I'll get nowhere with my request.
