Call on landline went to answerphone. The message - in a female voice - purported to be from the bank, saying there were two suspicious transactions this morning on my card (note that type of card was not given), one for £99 from Amazon, the other for £799 from Zoom, and that I had never used these services. The message invited me to press 1 to confirm they were genuine and proceed, or 2 to speak to Bank Security Department (note that the Bank's name was not specified). The voice sounded slightly urgent, but the flattish tone and odd intonation and pauses suggest it was computer generated. Exactly the same message, in the same voice, was left on my answerphone on 9th September, but from a different number (07440406370).
