I had two parasites call yesterday . . .
The first one, once she had finished gabbling telling me she was "Sarah", calling from the "BT Openreach Technical Support Department", started to scream when I told her that her claims were false. I just left the phone handset, leaving the call connected, and did other things.
The second one, male, told me he was "Gordon", calling from the "BT Openreach Technical Support Department" and asked if he could speak to the person responsible for "the Broadband". My reply was a plain, calm, single word: "No". Once again I just left the phone handset, leaving the call connected, and did other things.
Both "Sarah" and "Gordon" had very heavy Asian accents.
