I hate these type of things.... when I tried to call back just got weird engaged tone,husband advised me to turn my phone off!!!!peace but not practical .

This faceless sico has rung me three times tonight.Each time using caller ID have have rung back and the line is engaged probably because its warped mind is disrupting other peoples lives

At the moment companies can claim the insulation rebate directly from the government on your behalf, the company is calling to get details using an auto-dialer which calls 6 (i think) numbers at once, and talks to whoever picks up first, they take your details to the government and say that they've done your insulation and claim the money, it happened to me, i answered and said yes i needed insulation, they made a date to come to my house and never showed, so i went through another, more reputable company and when they went to claim were told that my house had already claimed.. Do not give your details to these ppl! They are scammers!

I Recieved a call from this number and i CAN'T call it back (It says "service unavailable") . Which is very wierd.  I'm not sure, but think that it might be a suspicious number.
