Problem with Coupon/Poor Customer Service

A few days ago I received from Ebay in my Ebay inbox on their site a coupon for 10% off any purchase made before November 30th, 2008.

Today I found an item I was interested in buying and checked to see if the coupon was still in my inbox on the Ebay site. It was still there and was still valid. I went ahead with the purchase only because I thought I was getting a 10% off coupon applied to the price of the item.

I won the item and went ahead to try to pay for the item and apply the coupon code. I got an error telling me that the code didn't work. I looked into it and discovered my email addresses in Ebay and Paypal were different. I did what the coupon said to do and changed my Ebay email so they were the same. It still didn't work.

I then got on a help chat with agent who was less than helpful and eventually closed the chat on me, even though I was nothing but cordial and patient in requesting help. After my incident I researched the issue on the internet and apparently there are many people who have had issues using these coupons.

Due to the fact that I complied with the terms of the coupon and was treated very rudely by agent in an Ebay help chat, I would like Ebay to credit me the $10.35 of the $103.49 purchase price of the item I purchased. Being a good Ebayer, I went ahead and paid the seller as this is no fault of theirs, but until this is addressed, I don't think I'll be using Ebay for any purchases in the future, which is a shame as I've always been a prompt and responsible user of the site.
