One of the older "duct cleaning" scams...amazing that it's still around...but so are the Nigerian bank scams proving that - a fool and his money are soon parted.
Have blocked their future calls to my home with my Panasonic phone that blocks 250 numbers.
I see that this call emanates from Seattle. Washington state has become not only the meth/crack capitol of the USA, it has become the telemarketer capitol of the USA.
On my business line, I have the Digitone blocker - it's wonderful in that you can block individual numbers and that it can BLOCK ENTIRE AREA CODES!!! I have all Washington state area codes blocked!
They can change their spoofed numbers but they rarely change their area codes.
The caller calls us daily in last 3 months. When I called back." thanks for calling back, if you are not interested, pleas click on 1 allows us remove your number 72 hours" Today it called 16:54, 10 /08/2013. It keeps calling back. many complains filed with www.800notes.com. It calls to 122/2013. It used other number to call people as reported to www.800notes.com.
This spam service has been calling my number for months, usually around dinner time, but today they called early on a Sunday morning. What is wrong with these people? I'm tempted to finally hire them and not answer the door when they come. If they complain I'll simply claim ignorance, that I never placed the order in the first place. Inconvenience is fair game, I say.
