Hi. You are the Buyer?
if so, a seller cannot demand extra postage costs if they have just made a mistake.
Plus a seller cannot leave a red negative dot for a Buyer. A Buyer can for a seller though.
I would pay the invoice showing winning bid and original postage cost. Buyers do not pay Paypal charges.
I would tell the seller that they are not allowed to up the postage just because they have made a mistake...plus Sellers lost the right to leave a Buyer a negative years ago and you have paid for the item and look forward to receiving it soon.
No one should threaten anyone over feedback...that is feedback extortion which can be reported to Ebay. I would be inclined to tell the seller that unless they stop sending you unpleasant messages then you will be contacting ebay who can read the messages between you. (Yes they can if sent through Ebay messages)
Hope the above helps.
