    5. Brian Scattergood reported "Boilers UK" with the number ‎0151357159 as Telemarketer

      7/18/13 4:30 PM

      I answered a call from this number. Automated voice asked me if I was interested in saving money on energy bills. I responded "yes" by pressing 2, to find out who was calling me. A Geordie female said that she was calling from "Boilers UK", and asked if I was a homeowner. I was in the middle of informing her that I wasn't, and I only pressed 2 in order to have my phone number taken off their calling list, but I didn't manage to finish what I was saying before she cut me off. Charming!
