Who is this? sounded like they were in a crowded area, asked for my mother, then hung up

Got call.  Did not answer they did not leave message

It is some company collecting $ for cancer.  They refuse to remove my number & hang up on you every time you call.  Since they wouldn't stop calling me, I called them for 2 hours straight & tied up their phone lines.  Hopefully they will remember me now & won't call my # back.  I m so sick & tired of this harassment by these rotten telemarketers....

Unwanted call

I receive calls from the Wireless Caller every day, but will not answer.   I believe it to be an auto-dialer.
