Called me several times this past week - on my cell phone - I don't answer calls if I don't know who is calling - simply because I am 70 years old and if you ain't one of my kids or grandkids calling I probably don't want to talk to you anyway - and if I do I will call you.....

These calls are annoying and aggravating.  At the beginning I would call back to stop the calls, but I have never been able to speak to a person in order to tell someone to place me on their Do Not Call Registry.
I stopped trying, because leaving a message did not help, they became more aggressive with calls, every hour.  At that point, I stopped answering, and the calls dwindled. They still call every other week or so. Maybe one day they will get the message and stop calling or they maybe they like the thought of being a nuisance.   Hopefully, someone can come up with a way to get rid of them for good.

Started receiving calls from this number.  Have not answered call.  I do not answer calls that I do not know.

This is some sort of freebie vacation offer. Most likely a timeshare scam.

they have called me everyday this week, have not answered.
