I had 43k on Delta Airlines and received a letter in the mail 6 weeks prior to expiration on how to keep my miles valid.
Air Canada/Aeroplan are being less than honest.
For an organization that has no problem mailing Aeroplan statements one would expect that they would be able to mail a letter to their "valued members" so that the member would be able to keep their miles active.
Further, the few times that I have written to any organization, they have always written back or called. I'm not saying that Rupert should have responded to her faxes direcftly, but someone should have. Air Canada's/Aeroplan's is just showing what they think of their "valued customers" and the "importance" they place on customer care.
