I recently bought a nightgown from a new seller, which arrived with postage due $2.84. She had charged me $3.40 for shipping. Although I didn't have to pay much more, I did want the seller to know and sent her 2 messages in one week requesting a refund. The seller didn't respond to either of my messages. I don't intend to leave her any feedback because I don't want to be petty, but I would like her to know that this is not good customer service and could impact her future as a seller on Ebay. What would you do--send the seller yet another message, leave less than positive feedback, or just forget it? Thanks!
