I'll never trust any e-Bay seller so easily even if his rating is high. Ever wonder how they get so much high rating that even Flipkart or Homeshop can't get? They sell counterfeit or cheap quality goods and most people just crib the seller or themselves for their bad luck. They don't care to rate those sellers at all. When somebody does rate them low, they call the customer and plead, cry, beg for a higher re-rate saying their life depends on it. If we don't fall for that, they call again and will offer you a full refund of the money and will ask you to re-rate them higher.
I know this because I experienced this. I bought a full housing for my SE K800i phone, which the seller claimed was genuine high quality replacement. The product I received knew nothing of quality. I gave negative rating to the seller and the above happened. He called me and asked to remove the negative rating. I questioned his product description and demanded to remove the words 'High quality' from the product description. He removed the description and called me again to remove the rating. I checked his other items and many were similar 'high quality' replacement panels for many other mobiles. So I declined his request again when he called and then he offered my full refund without return of the product. I yelled at him that I can't be a party for his cheating enterprise and declined again.
If any ebay seller pleads you for a higher rating please decline until it is an absolutely genuine case. This why every seller requests you to contact them before leaving a negative feedback.
