...there credit card? IE...Product was damaged in shipping by hired freight company...customer signed and accepted items as damaged and now wants all monies back a week later. I'm assuming since it was signed for and accepted at time of delivery, the customers credit card company would not let them reverse charges? Am I right?
jennifer, yes and the policy is clearly stated, if freight is damaged in shipping the customer has to file a claim with shipper.

Yes, the customers credit card company will have a dispute process and the charges will be reversed. The only recourse you may have is if the freight was insured.
