Purolator review: They simply refuse to deliver my packages. 1

I've twice had the misfortune of ordering products that were shipped by companies via Purolator.
They straight up refuse to deliver my packages, and lie about why they can't.
Their driver has claimed I wasn't home, "the business was closed" (?), their truck broke down, or just no reason at all.
Customer service does absolutely nothing about it. They provide the same nonsense excuses the driver does regarding why he can't deliver.

After refusing to deliver my previous shipment, I worked out an arrangement with the shipper to have Purolator deliver it to a retail store location. He talked to the Purolator agent assigned to the (very large) retailer, and confirmed I could pick up the item when it arrived at the store.
The next day - the package was left on my doorstep. No knock. No signature - even though a signature is required for ALL deliveries from that retailer.
The current shipment from Purolator is more of the same... They've had it for over a week, have claimed two obvious lies were the reason I haven't gotten it:

One was "sorting error," the other - which they've told Amazon - is that the delay is due to inclement weather. The weather is fine, and has been fine.
...and now, it's not even out for delivery.
The most unprofessional company I've ever dealt with, and I will NEVER buy anything from anyone who uses Purolator to ship, and I will tell everyone I know to do the same.
