Car ID Screwed me out of my money & product Cranbury, New Jersey

Placed an order for a owwd sah kit for my BMW was told  a specific time it would be shipped due to a car show I was attending.  over 6 employees LIED to me on shipping and the order.  I paid for over night delivery and was lied to never was delivered.  They claim mfg had made an error and would ship in 2 more weeks I told them ship everything but the piece which was bad they claim they shippied it to me after the date I left the state for the show.  I was gone 2 weeks and still no product.  They claim someone who they cant identify signed for my order the day after I left my home.  No one was at my home to sign for an order and they cant provide me with proof other than a tracking number claiming it was signed for.  Upon contacting the company they claim they cant do anything for me and they have fulfilled the order.  Problem is I dont have it.  Oh ya thats right I want to install two dash kits for the same car on top of each other.  Very poor customer service and you wait on hold a ave of 30 minutes to speak to a rep.  no one knows what the other person is doing in their own company.  Very un organized and now I'm out over $500.00
