Scam for on-line Christmas

I got one of those emails about a week ago supposedly from DPD,it said that an attempt to make a delivery had failed as there was no one at home to sign for it.
It gave a time and as I was suspicious because I was not expecting anything I checked the cctv and there was never an attempt to deliver anything.
It stated that if I did not reschedule the delivery within so many hours the parcel would be returned to the sender.
I deleted the email .

There’s an interesting guy on YouTube called ‘Jim Browning’, from Northern Ireland, who reveals how a lot of the usual phone scams are done, and can sometimes turn the tables on the scammers. Well worth checking out.
