"Duct Cleaning " scam outfit out of Chicago ( imagine that! ). Calls from many numbers, what they really want to clean out is your wallet. Tracked them down during the summer and confronted these criminals at the Elk Grove facility they used to be in, and brought the cops with me to fill out a report. I told them I was pressing charges and would sue as they have been breaking the law, telemarketing without checking the State and National DO-NOT-CALL list. The place was empty the next day, like turning the lights on and the cockroaches scattered, even the landlord said they paid in cash and he had no info on them. Cops didn't get any real information, the secretary gave him a few false names and didn't know anything else and the only other guy there spoke Russian and we had no translator. And why is there no call type catagory below for CRIMINAL?
