Please investigate and let me know why I DIDN'T win this auction. Is there a problem with BidSlammer software. If so I will need a full refund.

Hello Daniel,
Thank you for your question about this snipe. You did not win this item because you did not bid high enough. Look at the bid history link below. Someone placed a proxy bid about one hour before closing time. When we placed your snipe, you were immediately outbid because eBay increased the price to match the other person's bid.
