The new feedback system was brought in to protect buyers who have had bad experiences with sellers to be able to leave negative or neutral feedback without fear of reprisal or feedback blackmail.
Unfortunately some rogue sellers are abusing the new system by leaving positive feedback with derogatory comments. If this happens immediately contact ebay's help and support team and they will try to resolve the issue and if justified will remove the comments that the seller has left.
Some sellers are even resorting to the spiteful act of sending abusive emails, because they can not retaliate with negative feedback. If this happens forward all emails with the header displayed (see your individual email settings for this) to : u k c s webhelp @ ebay . com - (you will need to remove the spaces, the guide will not allow the link to be typed here) with a brief note of the problem.
They take this matter very seriously and will take action.
Another option is to forward them to the police and the senders email provider.
Hope this is helpful....
Update 22.5.2008 :
The ebay feedback system is becoming an unreliable joke.
I recently left negative feedback for a bad seller , who went on to send me abusive email, and what action did ebay take ? They removed the negative I left, so that the next unsuspecting buyer will have no warning.
After reading other peoples guides other members both sellers and buyers have been told by ebay that feedback can not be removed unless by mutual agreement, so where is the consistency ?
It appears that there is none.
A few months ago myself and over 200 other members were scammed by an ebay seller, so we all started leaving negative feedback, and you guessed it , the next day ebay removed all of the feedback even though the police are involved etc etc. After speaking with other members the same thing happened with the same user last year, and again the negative feedback was removed leaving no warning for over 200 members who lost money this time around.
So how can feedback be trusted if sellers can at the drop of a hat (email/phone call) can have negative feedback removed ?
The moral is always pay with paypal, they are far more helpful than ebay, BUT if you are not 100% sure do not buy, there are lots of other online shops and prices to compete, and sometimes its better to pay a few pounds more for peace of mind and a product guarantee.
Ebay used to be a great place, it's a shame it is becoming so commercial where power sellers seem to be able to do as they please and the small ebayers are becoming the silent minority.
INTERESTING TO SEE THAT THE SELLER I HAD TROUBLE WITH BLAMED ALL THEIR PROBLEMS ON STAFF WHILST BEING ON HOLIDAY FOR MONTHS ON END !!
THEY RECEIVED A BUCKET LOAD OF NEGATIVES, AND ARE NOW NO LONGER TRADING ON EBAY...SEEMS THERE IS SOME JUSTICE !!
