I just received this phone call from Officer Dennis Grey (Gray). It came to my smartphone that I only use for apps – I never give anyone the number, I don’t know what it is! Even though, there is always an element of doubt, even for me with my experience of reading 30,000 scams.
Plenty of clues confirms it is a scam. The very fact it was an automated voice, lack of personal details and just general bad grammar are some examples. There are others but this is not a training session for scammers.
