UPS stinks plain and simple. All things considered they have a huge workforce and they have the technology to get the job done efficiently but the legacy systems and irresponsible human factor is what drags this entire company down.
They hire *** near anyone who is willing to break their back and make minimum wage to haul, load and deal with your shipments.
These folks hate their job and management is incompetent. They seldom deliver packages on time and good luck if you EVER try to work with customer service....I try to choose Fedex if I can because UPS is the pits!!!
