i get similar emails, and even phone calls, today i had a recorded call stating your talktalk internet will be disconnected today, unless i phoned the number on the recorded message, i just blacklist the number among the many i have already blacklisted already, i get bank scams paypal scams ppi ones, house insurance scams...endless.
but i know they are all fake and not to respond to them, they just get on my nerves, the phone call ones i can tell right away, as they always have odd numbers and constantly changing, i know they are voip calls...google voip if you want to know what it is, they rotate numbers that you see when you get a call, and alter their number if you block them, so as to keep calling you, and they are not in the uk.
