"Jack Webster" - with a Indian/Pakistani accent - said he was calling from Telstra NBN and that my upload speeds were below 20 mbs. I asked Jack where he was from - he said Sydney, then changed to Melbourse. I said "interesting that you're calling from a mobile number Jack" - he said :yes" then when I asked him if he thought people were effing stupid - he hung up. Didn't even have to use my whistle!
