Caller ID says service call, when answered clicks to buzy signal........

Hi , how do you block them ? thanks

Hi everyone, all these anoying calls seam to the the norm now. I neveer answer my phone just let it go the the answering system. That is my only way to screen calls for now. Keep the post comming. Cheers . Don Folewy

When you ignore their calls it just makes their job easier.
You should answer with "hello" and wait for a live agent to pick up.
Pretend to be interested, stay calm and act agreeable.
The idea is to waste as much of their time as humanly possible.
When they have to answer calls from people who have no interest in their scam...they lose money.
Remember, it's an automated machine calling you not an actual person. If you don't answer it's no skin off their nose because the machine will just call you back later.
Get even and make them answer the calls they're making.

This number is calling my cell phone (which charges me after I've used so many minutes).  It is disrupting my day at work and is not welcomed
