Ok, I work for a competitor. Some large volume shippers use multiple carriers and it is not uncommon for packages to be given to the wrong carrier. We have Ontrac packages in our system quite often. This is rather common in the package transportation industry. The thing that makes Ontrac different from the other carriers is that when we call to inform them that some of their packages are at our facility, it can take days - sometimes a week or more - even after multiple phone calls, before Ontrac will come by to pick them up. We just don't have this issue with other carriers.
