Negative Amazon feedback - please help me respond politely

[Avago]

I've sold 100's of products on Amazon, I have 30 or so "seller feedback" reviews which are actually reviews of my products and every one is the max 5 stars. This info is quite difficult to find, at a glance it very unhelpfully looks like nearly all my products don't have reviews. The only customer that has managed to leave an actual product review has slated it and left 2 stars. She ordered in Oct, left the review in January and I'm afraid I haven't noticed till now since I work seasonally.

No request was made for a refund which I am happy give, even without the product back. I can reply privately and ask for negative feedback to be removed and if it isn't post a public response.

I'm trying to respond with out being passive aggressive, but I can't seem to manage it! I've 100% positive feedback on ebay too, I know I'm taking it too personally but I make the item and I guess I'm hurt.

Generally, less is more.
Say and do nothing.
Nothing you can say will remove her comment.
Commenting on it could be seen to imply that there is a case to answer.

Same applies on ebay.

Really........ do nothing?

When I shop on amazon/ebay I always read the negative reviews to see what's the worst that can happen. I am always reassured by sellers that have responded to criticism/ problems in a positive way....... 'I am so sorry you were unhappy with my work. I make everything myself and always strive to get it right. I am very disappointed that I didn't live up to your expectations and only wish you had contacted me so I could rectify.......' blah blah.
I am always a bit put off by negative comments that haven't been dealt with...... but it may be just me?

Thank you for the replies. I would be tempted to leave it especially after all this time if it could be 'lost' in all the general ones but it's so visible I feel I should do something.

Would you offer a refund - it wasn't requested, and I guess she's either used the product or its in the bin. Everything I sell is a variation on a theme so no point in offering replacement .
I always read the negative reviews too

If you go with the 'I am really disappointed you didn't contact me as I could have sorted this out.......' etc then you will show good customer service without having to refund. I wouldn't bother contacting the customer though- just leave it at that
Try not to take it personally- there are always moany people around who like to have a whinge..... can't please everyone :-)
