Called my cell and in a really weird voice (maybe foreign) asked to speak with me and badly mispronounced my name. My name is not hard to pronounce. He almost sounded like a computer. I just hung up.

Didn't answer, having recognized the last 4 #s, which have shown up repeatedly in past weeks as coming from varying area code/prefixes and even in variations of 800 #s.
Showed as being from "KELLI SPELL" this time.

This number has called several times, both our land line and my cell phone. Finally, I answered but didn't say anything like they don't.  They hung up fairly quickly.
Maybe it'll get them to stop calling. I can waste their time just like they can mine.

Woman from "vehicle processing department" is doing a "standard warranty checkup." She knew the model and make of our car. Asked if we still have car, what mileage is. Hung up when I insisted to know the name and address of her company. Probably an auto warranty scam like this - http://www.fcc.gov/guides/auto-warranty-scams 

Rec called from 217-679-4875 very forign speaking person knew all the info about our car year and model. Wanted to speak to my husband and when I told them we were on a do not call list they hung up. If I had been an older person I am sure info would have been obtained and scamed for sure.Sad times we live in .
