In case it happens to anyone else : ticketmaster doesn't make an investigation until it's been a full month from date of purchase... However, they have been very reassuring saying that if the tickets were lost in the mail or anything like that, that I won't have a problem replacing them. Of course, I am expecting nothing less than that ! But, it's nice that they say it right away... So I guess I have to keep checking the mailbox for another 10 days

My concern came because there is no tracking number... which sort of indicates that tickets have been sent to Canada Posts but didn't get into their system... They could be on their way or anywhere really... We will see... No worries to have : on top of that, I had purchased tickets insurance for 8 dollars.... When spending several hundred dollars, it's worth it.... So not worried here, just sharing in case some are going through this as well.
