Question regarding DSR scores

Hi


 


I dont post here often.


 


I have an issue with the DSR rating system. Up to now I've maintained 100% positive feedback with my buyers.


 


But when i looked at my DSR ratings I noticed that a few buyers have marked down my DSR ratings.


 


I am mistified as to why they have done this. 


 


Nearly all of my items are shipped with FREE Postage. I always ship sold items within the 1 day handling time and I automatically leave Positive Feedback for all my buyers.


 


I respond to all queries almost immediatly - using ebay Android app so i can respond within a few minutes.


 


How can i improve these ratings.


 


Its currently impossible for me to add tracking to my cosmetics range if I paid for tracking eg click and send then i would be making a loss.


 


Does anyone have any ideas Is my account at risk? I dont want to get a suspension because a few buyers decided to give me low stars
