A woman with a friendly voice asking for donations for Breast Cancer victims. I politely declined - maybe they were legitimate maybe not. Do not trust any one who makes cold calls ever under any circumstances.
called my cell. I did not answer (of course), and they left no message (of course). I do not have a smart phone so cannot block; instead, I put them in my contacts and assign a "no ring". At least I won't be interrupted with the phone ringing.
