I got a voice mail from them today. Because I was on the other line it went right to my call answer. They didn't leave a message. I could hear voices in the background (one sounded like a child saying "say hello" but I am not totally sure).  I have no idea what they wanted as no message was left.

I'm getting frequent calls from this Five 9 call center.  Haven't answered it yet to find out who the actual client is.

This is Five9 calling out of San Jose area in California... They sell call center software. They are an extremely legitimate company... They abide by all the rules...

I have used their service before and if you get calls from that number it is more than likely a return phone call.

I sent an e-mail to this company telling them I am no longer interested in their service. They keep calling, but don't leave a message. I'm not interested, but can't get them to stop calling.

Someone went to the website and put your phone number in as a call back !
Here are the phone numbers that the website logged as bogus!
Meaning these are the numbers they called from.
Feel free to use PRANK dial or prank owl etc.
To spam them back . They are scum debt collectors screwing with you .
