Unreliable company that fails to deliver, doesn't deign to inform when the package would arrive or if you need to be there to pick it up personally, and makes it purposefully difficult to talk to customer service. They put in less than minimum of effort to keep their customers satisfied. The customer reserving representative I was ona chat with today clearly couldn't care less about saving a transport of refrigeration-stored medicine to a disabled patient. I prefer to post via FedEx or USPS, and I dream of DHL being allowed to service domestic transports within the USA. DHL is by far the best. Avoid UPS at all costs!
