Caller: purported to be message from taxation office.

Call received on my mobile phone. Recorded message claimed I had a serious matter outstanding re tax and to avoid all manner of serious things I should press one. I did and a foreign fellow wanted to know my name and why I called. I said “you should know because you rang me” then I told him that anything the tax office tried to get me on would be a waste of time as I always beat them.
He hung up on me without making further comment.
