I get them on the landline which is in the directory, it's also in the public domain as with madam being a Councillor you have to have your details published.
I reckon though that as I annoy them so much they keep selling my number on, if I'm in the office I can average about 4-5 a day, mainly MS/BT internet virus scam but occasionally I get PPI or accident claim ones. .....(I must remember your answer).
You can get calls trying to sell you stuff all day long sometimes. A typical one was from Duotool in Aberdeen.
Mobile phone rings and very heavy Scots accent is heard
Me "Hello"
DT "Hello Dave, this is Duotool, I wondered if you're interested in any fixings"
Me "No, not today"
DT "But we've got some really good offers"
Me "I'm sure you have, but I don't buy things over the phone"
Usually this works but this chap isn't being put off.
DT "Dave, you say you don't buy over the phone, but have you never ordered a Chinese meal"
Me "No not from Aberdeen I haven't as it'd be cold and mouldy when I got it"
DT "You're a funny f***er aren't ye"
Funnily enough I never purchased from them.
