I had a temporary card that I was collecting points on for several months before signing up - I finally got around to doing this online and found that I was unable to do so and was instead issued with a new account and zero points. The cutomer service centre was pretty unhelpful so I asked them to delete my accounts and data. If it's this painful to sign up then I can't imagine trying to actually claim and use earned points. Definitely better rewards programs out there.
