Interesting report in yesterdays Times of a scam involving a set of headphones ordered from China's equivalent of Ebay although apparently it happens on several platforms.
Basically you receive a faulty set and when you complain you are asked to return it but are actually given the name and address of another new customer with specific instructions not to include any details of the fault or your address. So this individual set of headphones are probably sold 9 or 10 times before the platform eventually closes down the scam.
Wonder who first thought of this ingenious scam
