Glad this worked out. For future reference, and others reading along, you should not mention feedback when trying to resolve an issue like this.
ebay may consider it to be feedback extortion. See their policy here:
http://pages.ebay.com/help/policies...tortion.htmlHypothetically, had the seller refused to refund, and you left negative feedback,
ebay could have removed it based on this policy, resulting in a lose/lose situation. Unethical sellers (which does not apply here) know how to work this policy.
