Does anyone know Amazon's FedEx Account Number or how to find it? I would call and ask seller support, but they can never give a straight answer. I'm here now due to them giving me a run-around.

Months ago, I purchased shipping through Amazon's shipping services for a sale, only to come back about a week or two later to find I had been debited over 100% more. When going through the details on Amazon, I discovered that Fed-Ex wrongly adjusted the item's weight to twice the amount, which caused Amazon to debit me a total shipping cost of more than twice what I paid for the label.

When I contacted seller support about this, I spent hours on the phone with the agent, only to be told that I had to reach out to Fed-Ex directly if I wanted reimbursement. But now that I've found the time to contact the Fed-Ex reimbursement team, I've been told that since I bought it through Amazon, they should be handling the issue since their account processed the payment and got billed. But the agent says, at the very least, I need Amazon's Fed-ex account number to try to process any claim. Agent says Ii usually starts with a 5 or 7 and is nine digits.

Does anyone know how to find that Fed-Ex account number or how to help? This is such a headache!!!
