I had it yesterday, it was a bloke with southern accent. He was triying to offer all these packages and deals and wanted credit card details over the phone.
The phone number came up as blocked, I personally would not give any one any of my details if their number was withheld, blocked, looks funny or not showing for some reason.
In the end I just put the phone down on him, usually I do this straight away on these sort of numbers, but because he said he was from the police you listen for a little bit, he even said he will have a quick word with his sargent to get a better deal, you just heard him talking to hisself, sounded really silly doing this.
