My suggestion to you is be patient.
I cancelled a lifemiles ticket. The operating carrier was United. The $50 cancellation fee posted in 1-2 days, but it took 5 days to be refunded the miles and taxes. Even after that, United.com showed "This reservation has been ticketed and confirmed". Only on the day of original departure, the ticket status became 'Refunded'. So in your case, your reservation may have been cancelled indeed and you are most likely to be charged that cancellation fee twice.
