My package had international tracking that switched over to Canada Post once it was in Canada, cleared customs and ended up in Ottawa (where I live) but was never sent out for delivery. That was on February 5th, I then contacted the seller and asked them to inquire to Canada Post about the whereabouts of my package. Tuesday (10th of March) I got a letter from CP asking if I had received the package in question or if it had been returned to sender. I check both no boxes and sent it to Canada Post.
Waiting to hear back from them, apparently they are going to investigate/look into it?
