These scumballs are General Contractors doing work in the area using a spoofed phone number trying to rip off the consumer. Don't give them the time of day.
General Contractors looking for and so on. Hang up. I try to get in touch with a real person. They hang up when I ask them if they looked up my number in the Do NOT call list.
I answered it but the connection was bad so I just said, "I can't hear you" and hung up. I already knew it was a telemarketer anyway because all calls I get from the 310 area code are telemarketing calls, mainly construction with a few so called duct cleaning ones thrown in. Also calls from 562 and 626 (my own) and 714 are always telemarketing calls.
