Ordered from Amazon, They didn't leave any notice, Purolater claim they tried to deliver the package twice on the same day ( i work from home ) but the city on the tracking is the same as the location of their warehouse. The tracking does not show any attempted delivery at my address/city , It looks like a scheme : pretend to attempt delivery but dump the package at a pick-up location so they don't have to deliver the package. I have escalated the complaint to amazon and asked them to stop using Purolater.
