Hello rajelectroniks,
Your Profile shows that you are good seller but unfortunately, you have not considered your online buyer as offline buyer. If the buyer purchase anything from any shop in the market can the seller pack it in Cigarette Box and you as a buyer can you accept such pabking. This is highly disregard to any buyer. Seller will have to be more cautious when he is buying online because he is paying beforehand without seeing the item. In such circumstances seller's responsibility increases.
Anyway, this is a mistake on your part. But the buyer could have contacted seller for clarification than to take such harsh step.
Only options left to you, I can suggest:
Write to buyer apologizing for any mistakes you have done unknowingly without any bad intention, and request him to review the Feedback. If he agrees, send him Feedback Review form.
Secondly, if buyer do not agree to review the Feedback, you can file the case in Community Court.
Learn a lesson for dealing in future to cinsider buyer as if he is buying from your show-room.
