Purolator review: Shipping and delivery of package

At least 3 different shipments 2 I paid extra for our of pocket for Purolator express professor had thrown in tracking mechanical delay. That is in just over 1 summer season. It seems when they don't hold up to the prostate express overnight shipping they throw that in there so no on call asked them pay them back or hold them to account but myself who has equipment shipped by Shaw Purolator express it has happened so often is beyond what most delivery companies have had happen. Way to often to now believe it. 2 of my overnight shipments were extended to 4 days because of mechanical delays them laziness if drivers who don't come to building back door managers office has window in the back entrance as well are an NP client clinic and have told me at end of day no they saw no Purolator truck but says attempted delivery. Also is a buzzer button can press and the front desk or manager keys them in. On I've shipments a driver diff this 2 days in a row. Thank goodness saved the tracking sent it to Shaw the shipper on hold there over night delivery they pay for takes 5 days. They p Thanksgiving me for letting them know so they so paying high prices for service professor doesn't give. Either someone needs to go through their whole fleet and makes sure they are optionally maintained and okay to drive fly whatever so these content mechanical delays stop or they need to start doing their job and deliver in their promises they make people pay for. I ordered something had it sent by Canada post them at same time ordered something else sent paid for Purolator overnight Canada post got here first
