Unfortunately, for every one you block, two more pop up. I've cut down on a lot of the calls by not giving my true phone number to anyone anymore. However, that doesn't stop the auto-dialed robo calls.
I got one call today from some bitch asking to speaking to who was in charge of the bottled water orders. When I asked her what the heck she was talking about, her reply made it obvious she "thought" I was a business. I coldly told her she had a residence and I didn't use bottle water. She quickly replied they were supposed to be calling only businesses and would have my number removed from the list. If she was supposed to only be calling businesses, why was she calling after 6 PM? Lately, I've been getting quite a few calls from businesses trying to find ways to weasel around the Federal Do Not Call List.
I'm seriously considering Skype since my computer is up 24/7. An alternative is to get a second cell phone account and a gizmo I saw that will link an el cheapo cell phone to a regular land line type phone via bluetooth. I could leave that phone at home permanently connected to a charger.
