This is a scam mail saying you ordered Micorsoft Surface Pro and it was shipped to you and saying 'paid on line'. Accidently if you call this number, they will say it seems your computer is being hacked and they will take of this order in order not to damage to you financially. At the end, they will say they are concerned about your identity security and they can help identity theft protection. They will request to purchase two $500 Google Play cards and let them know the card information. Once you do it, that will be it.
