Received call from them today at 5pm just dead air as well.

I don't care who it's from and who they are.  I know it's a steaming pile before I answer as my call display shows V08022329360043 as the caller.  Really?  So for all of you out there who can't stand these butholes (and those like them), here's how I handle them so they don't call back.  Get an airhorn (or use your home smoke alarm), and when and if you get a real person, blast their ears so they can't use a phone ever again.  Do I feel sorry for them?  Hell no.  I don't feel sorry for criminals trying to scam me.  I know it works as I've very very rarely been called back by the same scammer twice.  Syanora suckers!  What's that?  You can't hear me?  Hope you can read and to any potential telemarketer/scammer who might be reading this, beware your ears if you call me.  And if you ALL did this, they'd soon learn it's not worth their time as they wouldn't be able to hire anyone unless they actually like the sound of an alarm piercing their eardrums.

This number keeps calling my house asking for duct cleaning service. ?This is an unwanted call.

No one at the other end

The trick is to get onto the "not worth the trouble" list of these telemarketing companies. I'm not talking about the "do not call" list where you politely ask to be taken off their calling list - most companies either illegally ignore the do not call list, or they follow the letter of the law which allows them to start calling you again once a new "campaign" is underway.

Get on their "not worth the trouble" list. Telemarketing firms don't advertise the fact they have this list, but they all do. You might think the most effective way to get on this list is to be rude, loud, and abusive - but it's not. It takes 1/2 a second to hang up when somebody becomes abusive. There is no cost to the company - and certainly no cost to the management who don't give a s**t if their frontline workers go through hell every shift.

The surest and best way to get on the "not worth the trouble" list is to WASTE THEIR TIME. Pretend to be interested in the duct cleaning services. Ask lots of questions. Pretend you don't understand what's being said, and ask them to repeat themselves. Tell them excitedly "You probably charge by the duct! I'm going to go count my floor registers right now!" When you come back after 2 minutes (don't leave them hanging for too long) say "okay that's six on the first floor ... let me go check the second!" Then you can go check the third floor, the fourth, the fifth, etc. Eventually the lesson will sink in that they are being played and that you just wasted ten or more minutes of their time. But if not, feel free to explain to the dense telemarketer at the other end that you just deliberately wasted their time - time they could have spent making a sale - and that they should tell their supervisor that your phone number is a profit killer.

Here's the best part: if you employ this strategy, you'll soon see a dramatic reduction in the number of telemarketing calls you receive. And if a few thousand people employ this strategy, it collectively starts to break the profit model of the entire telemarketing industry. These sweatshops are relying on the fact a rep can make X calls per hour with a Y% conversion (sale) rate. If X drops significantly, Y no longer matters.

They called me too. But I don't pickup and let the phone take voice messege. But they don't leave messege. I dont pick up any call saying long distance.
