Namarrg0n is correct on all points I am afraid, once you finalize SR support cannot help you retrieve those coins even if the vendor is proven to be a scammer and has their vendor account banned, once you have released the coins they are with the recipient and the only way of getting them back would be from the vendor. I am sorry your first experience wasn't a good one, it happens to most of us when we are first finding our feet on here, that is why it is so important no to FE and stay within the escrow system. There are vendors out there who will let you stay in escrow, try sending them a polite introductory message so they can see you are a level headed person who will be easy to deal with, I always suss out new vendors with a pm or two before buying from them for the first time as their response can tell you a lot about how they operate and how long it might take for them to respond, e.g. if I am waiting a week to get a 3 word response I probably wouldn't order based upon that factor alone as that says to me they are either too busy or too lazy to provide a good level of customer service, especially if you run into difficulties with your order. And before any vendors flame me for making that statement I do fully appreciate that vendors get hundreds of stupid PM's every day asking retarded questions that could be answered by just taking the time to read the vendors page and responding to each one is very time consuming, those types of question should be responded to with a "read my FAQ".
