I had booked an MTV Sunglass and Watch worth Rs 749 on Aug 13. On Aug 23 or 24,I left a feedback of the seller(Goodwill Enterprises). I had given it just 1 out of 5 stars as rating. I want to review and re-rate it now as he contacted me and told me that he had initiated the refund on Aug 16 itself. I received the refund on Aug 24th. So i would like to re-rate the seller's rating from 1 to 4/5, as he had returned me my money. What should i do to re-rate? I dont want to spoil his reputation.
