I recently recieved a non reply email headed 'HMRC tax rebate' saying that a tax rebate of about £250 had not been claimed, and I only had a short time to do it by confirming who I am and giving my bank details for it to be paid. If anyone get this phishing email, do not act on it. I forwarded it to HMRC who are going to follow it up and reminded us that they never send emails with rebate details or anything else.
