I received two calls from this number today. In the first instance, after a lot of crackle on the line, there was an unintelligible squawk, so I hung up. In the second, I was asked if Mr. Atkins could come to the phone. I replied that there was no Mr. Atkins at this location. The caller then asked me to confirm the number they had rung. I didn't - I just repeated that no Mr. Atkins had access to this line, and hung up. Incidentally, I have had previous calls (which I didn't follow up) asking for Mr. or Mrs. Atkins.
