Moment,
I can understand your concerns and I know UPS is a big company. Many of my non-UPS friends and relatives are small business owners who rely on UPS for timely delivery of supplies and inventory. We're not adversaries, but this is our small way of helping you. If there is in fact a service failure in your area, you have every right to complain. To anyone who has been with the company for a while, potential service failures are taken seriously. Having said all of this, however, I still cannot understand how your packages are allegedly staying on the same truck for 2-4 days at a time, if that indeed is the case. I know where I work, nothing is stationary for very long. More often than not, as soon as one trailer pulls out, another one is pulling in to take it's place.
