I'm sure it was but feel a bit unnerved now. Had a phone call claiming t be from HMRC accusing me of committing tax fraud and saying there is a warrant out for my arrest and my assets will be frozen (bank account seems fine - just checked it). The man sounded foreign and it wasn't convincing at all. I ended it when he kept saying 'why did you do such a thing, m'am?'
I didn't give any details except confirming my house number and postcode, which I obviously regret now. Did I do right to end it and can I report it to someone?
