I shipped my car from Indiana to my uncle's home in California. After the communication with Misty in PDQ auto mover, we signed a contract stating that my uncle went to work from 9am-6pm and no delivery during this time.
PDQ is a broker and they give my shipment to carrier with Philly Express Group LLC. The driver was Roy. When he delivered my car to California, he called my uncle saying that my uncle must go back home now for picking up the car immediately!! That is happened on Friday, April 24, at 3pm!! My uncle was have an important conference!!
However, my uncle left the conference and went back home for my car delivery.
How can the service be like this? What's the power of contract??
Then, I contacted my agent Misty in PDQ Auto Mover, but got no reply!
