I have. CP's response was the absolutely absurd "we do not require couriers to deliver packages provided to them for delivery." My flabbers were legitimately ghasted at that response, and is when I completely gave up on them ever becoming a legitimate or remotely reliable delivery service.

Honestly, to this very day, I still struggle to wrap my head around the idea of a business that, as a matter of policy, do not require their employees to do the work they hired them to do.
