There are no responses when I say Hello, or there is a couple minutes of a recording.
Also one call was regarding changing my interest rate.
After all the  notes I read, I too will not respond to this number.

These automatic connecting phone calls are a pain in the butt,
and someone should put a stop to them.
For all of us DO NOT GIVE OUT ANY INFORMATION.

Just received a call from this number stating it is my last chance to lower my current credit card rate. They can charge what ever they want I don't have a credit card.

In response to previous message. Mybe you need to get a credit report. Just to be sure.
