How to appeal to this outrageous charge without proof on my account by eBay through FedEx shipping :

Question

I bought 2 labels through eBay with FedEx for my items that have had the same dimensions and weight for years, and because of the price of the labels I decided to take the risk of getting them, and it was a big mistake. The tickets are a problem, these people at FedEx use a third party, USPS, to handle the boxes, and then the night staff sent the wrong information to FedEx and eBay charged me twice the value of my items. And then they washed their hands saying that I have to call FedEx to resolv...

Two rules: Never use UPS or FedEx through ebay and never use the UPS/FedEx service that uses USPS for the final delivery. Open a free PirateShip account and ship UPS for better discounts or use your own UPS/FedEx account and keep ebay out of the middle.

Now you for current problem:

Because you used eBay’s discounted shipping rates, you cannot dispute the charge directly with FedEx; it must go through eBay.

Gather Evidence: Take photos of your package with a tape measure showing the dimensions and a photo of it on a scale to prove weight. Include tracking number and ebay listing Item Number.
Contact eBay: Go to eBay Customer Service and request a callback or use live chat.
Submit the Dispute: Inform the agent you are disputing a FedEx adjustment.
Wait for Resolution: If approved, eBay will credit your account, a process that can take time as they work with the carrier.
