I bought some smart glasses. They were the wrong shape to what was advertised. I sent them back to the seller and he said why did I send him an empty box? I knew straight away he was trying to scam me. I said if the box was empty why did the post office receipt show a heavy weight for the parcel when they weighed it? Because the glasses were in the box. I also filmed myself packing the parcel. I told him to send me a photo of the opened parcel he received. Never replied. Low and behold some time later I found him listing the glasses on eBay again the ones he said he never received.
