Call from an obviously spoofed number and a dimwit who claimed to be calling from my "telephone department". Even when I queried what a telephone department was, he wasn't deterred, telling me they were going to block unwanted calls to my number. (If only!!) I said, "That's good" and ended the call.

Left the phone ring out then rang the number which answered "this service is not connected" Probably spoof call. Beware
