Did your call go through? I have tried calling them a couple of times and I am also calling from the US. After selecting a series of options and just when I am about to be transferred to a representative, this message is played:
We are sorry the toll free number you have dialed is not available from your calling area SCT 11.
This is the number I've been trying: +1 613-944-4000
Did you try some other number?
