Hi. If that's you with the same username on Ebay with only three feedback, you don't yet have a DSR. It becomes available when you have been given at least 12 ratings.
Where to find a seller's detailed seller ratings
To find a seller’s detailed seller ratings, click the number in parentheses next to the seller’s user ID. On the seller’s Feedback Profile page, you’ll see the detailed seller ratings in a table on the top right.
Tip for sellers: Visit your Seller Dashboard to see how your buyers have rated you. You’ll see your ratings and find out how they compare to those of other eBay sellers.
