Just got a call from them at approx 8:30 on Boxing Day evening. Foreigner (no offence to anyone) with strong accent, much noise in the background, a lot of shouting. Had our names and when I asked who was calling he mumbled something, then "Duct Cleaning". We're on the National Do Not Call List- He's breaking the law. I asked him to take us off his list and he said "Shut up, B----". Nice! Then when I questioned what he said, he responded with "Sure we will do that for you". Creepy. Do not like these random calls at all and really tired of getting them and having to pay for call trace to find the numbers. Argh!
