I received a call and the guy asked for my husband by his first name, I said he wasn't available and could I tell him who was calling. Answer was "It's a local charity, we'll call back" Well not from that number they won't because............
I have a sure fire cure. It's called call block. Bell offers to block up to 12 unwanted number...dial *60 immediately after the call and follow the prompts. This is not a scam...check in your Bell phone directory under "Smart Touch Services" in the 'Call Privacy' section...right hand side of page.
Also many wireless phones offer to block up to 30 numbers...they ring maybe 1x and are cut off. On my Panasonic phone I just bring up the number under 'caller id', press 'save' and there is an option for call block...scroll up to it and press and follow the remaining prompts. Once you have filled your 30 numbers you have to go in and delete one of the older ones to add a new one. That's found in my menu under 'Initial settings' then scroll down to call block.
Asked for by my last name, when I asked what it was about he asked if I had time to talk , I said what is it about he said well do you have time to talk. I once again said if you tell me what its about I awill let you know if I have time. He said he would call back when I had time and hung up.
