Autobuyer scamming Auto Trader advertisers by charging £80 to send buyers who don't exist...

I have had two emails from people wanting me to pay a representative or haulage company from overseas via a bankers draft. My main concern however is a company called 'Auto Buyer' who contacted me and told me that they worked in partnership with Auto Trader and for a fee of £80 they could sell my car as they already had a list of people on their register matching up to my car. The idea is that they have registered clients looking for a particular car and when it becomes available they inform their client and pass on my details. They said that they had a 95% success rate within the first five days and my advert would be kept on the Auto Trader website until it had sold. Once the sale was complete I would then get my £80 'deposit' back. Needless to say I have not heard from them since making the payment. My car has not stayed on Auto Trader's website because they are an independent company and do not liaise with Auto Buyer. My car has not even been put on their website either as promised. Auto Trader are aware of this and have confirmed that they do not have anything to do with Auto Buyer. This was also a sham and I am now in the process of trying to get my £80 back. Trading standards have advised me to write a letter. I would be grateful for any guidance you can give.
