Solar scammers using this spoofed number multiple times by varying the last two digits (31, 33, etc.). They never leave messages, trying to catch victims live to extract personal information.

got a call and I didn't answer and they didn't leave message; must be scam!

They keep calling. Usually don't answer, just let the machine take it but they never leave a message. If you call the number back, you get a really stupid message on their answering machine. Have asked them numerous times to stop calling but they still do. Maybe I'll be as annoying as they are and keep leaving messages on their machine!

That's probably not too good of an idea as you may be paying a mean price for the calls, and wasting minutes while confirming your number is working. They could be looking for a live voice or leaving a message might cost them. If you can do it, turn off your answering device, but do not return the calls to mystery numbers.

This is just the latest of an ever rotating number of fake phone numbers and spoofed CIDs from longtime solar scammers. I have a 1500 number call blocker so why they waste their time with me is a mystery but I guess an autodialer never runs out of patience.
