I have ordered an item does not match what I have ordered, the item a heater would, weigh about  2.6 kg , watched the tracking of it via Australia Post ,when it arrived it was an envelope weighing satchel 5 grams with a tooth brush in it , it matched the tracking number that's about it now waiting for the returning process if the seller accept it , if not wouldn't know what to do , about the same time ordered an android unit for my car with all the specs provided by the seller , when it arrived and opened it it didn't match what they have advertised , the seller responded, send a picture of your dashboard , so I did , the answer ,we'll be looking for one to match  your vehicle , all I wanted was the same as the one in the picture with the same specs that they have advertised , ( whats going on ))so looked at it , closed in its box same as it was got the return sticker, and  have sent it back ,now waiting for the result .now this is getting too much

guess it was a scam , got my money back , thanks ebay  ,I was about to give up losing confidence in buying , after this happening I bought another heater ,first think I have done is test it ,it works , then gave a five star to the seller , so happy just can not describe , I had a good run buying from ebay never a problem but this last few weeks I had nothing but problems and the heater was just one of ,now I hope It'll get back to normal the way it was
