Hello 'deegucci',
Now, now, - no reason to go off in a huff. You only need to sort out how to make the most
of the "new improved" (cough cough) feedback system.
Have you seen this link about it, that explains all the ways and means feedback can be removed?
http://pages.ebay.ca/help/policies/feedback-removal.html
There are all sorts of related links about policies and procedures to click on as well.
Basically, - a seller can get feedback removed just for the asking. That's cynical, yes, but not
so far from the truth.
In future, if you have a sincere gripe about something, first try to get the seller to remedy the problem
for you by sending a gently worded note to the seller.
If you happen to find that very rare seller who tells you to jump in the lake, before leaving any feedback
call ebay. Find the words 'Help & Contact' at the top left of the page. Choose the Contact eBay and
click your way to a phone number and pass code.
The reason for placing a polite and calmly worded call to ebay is if you feel the seller has left you no
choice but leave something other than positive feedback, explaining this to an ebay phone attendant
will help you with what to say, -- and greatly lessen the chance it will be removed.
As you can see from the above link, almost anything qualifies for removal. But if you read a seller's
incoming comments, you will see you can distinguish between positives where the seller has clearly
gone to great lengths to make buyers happy, and those where the buyer is simply glad the item
showed up.
Happy shopping.
