Called, annual fee is due in about a fortnight (wasn't exactly sure of the date, but later realised it's the same date as the charge of the previous year - not when the card account is opened/activated).
Asked about the $450 travel credit and if another one is given next year, they advised no - it's just a one-off welcome offer.
I then asked to cancel, the same guy put me on hold and went to "process a review".
Came back saying that no points could be offered, but he would try again in a week and call me back.
How soon before or after your annual fee was due to be charged did you call?
