how do i make a complaint about a seller

[dhawke2012]

my item is not expensive, BUT i feel that i have been unfairly treated by the seller.  (im autistic - althought that should make no difference).  the seller has a mulit listing of coins and an image of the best examples.  some multi listing sellers have images of the exact coin you will receive.  i asked this seller to send me an image of the exact coin and he replied: "sorry im afraid that not viable with an item costing 99p but thanks anyway" (quoted from his email). so when i did the review (in an honest and frank way) i said "wanted to see pic of actual coin, told it didint cost enough, take pot luck".

the email i got back from the seller quite frankly upset  me severly and frightened me "re: the recent damaging and untrue feedback left by yourself... your false statement needs to be removed.."

which i duly did giving five stars all around and updating comment to "thanks".

i now find that seller has banned me from buying anything more from him, probably a good thing, but even more annoying the coin i asked for was a 1914 and the coin i received is a 1918 and now i am too scared to even ask for the refund in case i get even more abusive emails and worry that he might ban me from the whole coin collecting section of ebay.  my ignornace, i dont really know just how much power these people have. 

i have brought 81 coins and not had any trouble from 80 differnt sellers.

i also note this seller has asked 98 people to amend their reviews so he can maintain his 56874* rating.

i feel i want to make ebay aware of this, after all coin collecting is a nerd kinda thing so more autistic people must be out there doing the same thing.

is there a way to make ebay aware of this? preferably without getting myself banned from coin collecting in the process.

thanks for reading all that detail.

It is your choice whether you buy or not. If you receive an item which isn't as described, or which doesn't arrive at all, just read the Money Back Guarantee and follow the instructions to get your money back. The MBG is on every listing, and in various other places across the site.  That, along with leaving appropriate feedback, is how you 'report' a seller to Ebay.
