the woman called and asked for one of our employees, but refused to leave a message! AHHHHHHHHH I hate answering calls like that!

i got a missed call from this number and no voicemail was left.

I get calls from the number listed above asking for a certain person that I am not aware of.  Is there anyway to get someone or somehow to stop these harrasing phone calls?

I keep getting constant calls from these 602-263-1141, 602-000-0000, 866-376-1968 numbers and some automated voicemail is left to call, I called back and no one answered.  
How do you get these people to STOP calling!???

she gave her number as 602-263-1141

I called this number 877-745-0426 and spoke with a woman who acknowledged that the person who they were trying to contact is not me and said that she would remove my number from their system but that it takes 24 hours.

We'll see if the calls stop.

It was NCO Financial Systems.

I am repeatedly called by this automated calling system urging me to call their office.

How can I stop their calls?

some company calling me from these numbers.
602-263-1141, 602-000-0000, 866-376-1968

they have been calling me for months. Even thought I told them that I am not "Fransisco" they keep calling. Also my phone no are in "Do not Call list". Soon I am going to file a complaint about this company. This is really annoying.
