I first heard of this scam about 8 years ago, luckily the recipient realised it was a scam and wouldn't give it to the man who called to "collect" it 15 minutes after it was delivered.
Unluckily, a friend was taken in it by it, this week.
If ever you receive a very expensive parcel of technology, ie, I phone,
I pad computer etc, that you have never ordered, from a company, you have never dealt with; a courier you have never had dealings with, especially an order you have you have never placed with anyone whatsoever with. IT IS A SCAM. Do not hand over
the item when 15 minutes later when person arrives at your door to collect it as it had been wrongly addressed to you. Tell them you have spoken to the sender. (even't if you haven't), This usually happens at the weekend,so you won't always
be able to verify the sender, if they are closed. If someone turns up to collect the item, just tell tell them that you have been in touch with the sender who is sending a verified collector for the item later in the day. They will not hang around
if you refuse to give it to them.
They are now more sophisticated. They are sending verified courier companies 15 minutes after you receive it, so if a verified courier
turns up to collect an item to be returned and you haven't been informed in a advance,they will not be sure what they have been send to collect unless you mention that you have received an item that has been "wrongly" delivered to your address and you suggest
that this could be the item and you hand it over to them.
The scammer takes 15 minutes to get the item collected, this is because the telephone number on the label is not your correct
number, but a dead line. You may notice this and and question it Also if you do ring the sender and get through, they will ask you security questions and know that you and they have been scammed.
