They collect random names of staff at my company and ask to speak to them, offering no further information as to the nature of their calling until they speak to that member of staff. Don't bother answering, they're clutching at straws.

02038806230 called at 9.27am on Tuesday 12th March 2024. Not recognising the number as being genuine I did not answer but let it go to answerphone as I believed it to be a nuisance scam call. As I thought no message was left so the usual scammers who should be drawn and quartered for the public to see.
