Fraud.A warning.Please read.

Yesterday I was scammed of £20.000 by someone
saying to me they were the police.He gave me his name and number and said to dial 999 to check it.He had tampered with my phone so I didn’t get through to the real police.He told me they were investigating fraud within my bank and I mustn’t phone them or it would jeopardise the inquiry and a lot of people would lose money.All very plausible.I even asked to speak to his superior and he had someone lined up for that.
I have now got the real police,my bank and Action Fraud involved.
I don’t know whether I will get any money back.
I just feel sick.
