need to report a member

[latreshas]

there is an ebay member who contacted me and is threatening to get me into trouble for selling a mixed coupon lot , ebay has a section for selling coupons , this person is not interested in buyingthe coupons , but wants me to remove the listing or they say they will turn me in to the coupon manufacturer, i have blocked the member fro buying fromme , which should also stop their communication to me , i did remove the listing (only because i was already going to remove it ue to the fact it was accidentally double listed and i already sold it ) but i wantto turn the member in for threatening me over a type of listing that ebay does clearly allow sellers to sell , andtheir demanding people remove their listings , but i just keep going in ircles on the help section unable to actually reach a page where i can turn someone into ebay who has not actually purchased an item fromme , help anyone ?
