There is a comapny in Chicago trying to scam people. They say you have a summons to be served and they want to set up a time to serve you (no summons service does this) but if you want, you can call the number to stop the service. When you call you will have a fake lawyer try to make you pay some amount on an old past debt. for me they tried to scam me for a court case that was dismissed 3 years ago, that’s when I did a reverse phone look up on them and found a lot of new complaints starting in April.
Here is link to the complaint site. https://www.whitepages.com/phone/1-866-217-8948
They also called me back on this number 312- 265- 6880, that's how I found out there in Chicago.
I have called Chicago PD and emailed the phone carrier Vonage to turn them in.
