Increased Shipping charge fees

[babyneicey1]

I shipped a package a month ago, now eBay is saying FedEx charged me an additional $43 bc my weight was 7 lbs more than the label. I dropped the pkg off with a representative at the FedEx, they gave me a receipt. If there was an issue they would have told me then and I would have chose a different shipping option. How do I dispute this? I can’t seem to reach a live person with EBay customer service.

FedEx checks the weight and size of packages as they travel through their system.  If you had already purchased the label the agent would not have checked the package when you turned it in.  The machines caught the problem while going through the system.

There is little chance  of fighting these additional charges as they are imposed by the shipping carrier and eBay just passes them on.
