UPS, Franklin Park, IL - ITEMS NOT DELIVERED-UPS claimed delivery of packages from two different companies at the exact same time. Although home all day did not receive any delivery, never a doorbell ring. Driver should have been required to return where all packages were left and deliver to appropriate address. Apparently this was too logical. With driver errors such as this, when drivers return to the duty station, waiting up to 10 days for an internal investigation is a problem. Meanwhile I, along with other customers with a similar issue, are negatively impacted. (My items exceed the cost of $1,000.) I am left with expenditures and no items. Words cannot adequately describe UPS' substandard deficiencies in multiple areas, e.g. delivery (including driver communication), customer service access, complaints, investigations, website only to file complaint, etc. Before using UPS to deliver anything, I would personally take the item and deliver it myself, no matter the location. If a rating of minus 10 (-**********) was offered I would not have rated UPS one star. Best of luck with this carrier as whether you receive your item is indeed "the luck of the draw."
