7707702500 called today said she worked on behalf of UPS USPS and other freight carriers asked survey questions regarding shipping never tried to sell me anything just asked questions on Qty., Weight, and distance of shipping. Seems to be collecting market data to sell to logistics companies so they can try to sell me stuff.
I use RingCentral (which is like Vonage) and received a "missed" call notification from 770-770-2500. Odd because I don't know anyone in Georgia and odder still because I have received a "missed" call notification from 770-770-7700
