No notice of delivery attempt; not a call, not a slip of paper, nothing.
That's because there was no delivery attempt.
Instead, they sent my item back to the warehouse and said that I refused the delivery.
I wouldn't even have known if it weren't for the e-mail from the manufacturer stating that I had cancelled my order and I was getting a refund.
Thanks for wasting my time, Canpar. Just as bad, if not worse, as both Puralator and DHL.
