A Simon will call you from London with a collection from a Pri/address local to you, with delivery to Mr Tallar at a commercial address in North London in this case Willesden but then change delivery to a shop in Hatton Garden, where he will agree to meet the driver outside the shop after you call him on mobile.
If any of this resembles the job you get its likely a dodgy card
I've got a £100 that says so.
