I've had consistently poor experiences with UPS deliveries. Parcels are frequently late, customer support is unhelpful, and the delivery personnel in my area are often unprofessional. While I've had issues with UPS in the past, the last two weeks have been particularly problematic. Three recent orders (where UPS was the carrier chosen by the merchant, not myself) have highlighted these shortcomings. The first parcel arrived a day late, which is typical for UPS. The second was delayed by two days. The third is currently stuck in customs. Its estimated delivery date has been changed three times, with the latest change pushing it back by a full day just moments before the scheduled delivery window. Frankly, UPS struggles with the fundamental aspect of their business: timely delivery. It seems they excel only at failing to meet expectations.
