I got a call from them too. When I asked them to stop, they starting calling me 4 times a day. I reported them to the Federal Trade Commission. Here's the link: https://complaints.donotcall.gov/complaint/complaintcheck.aspx
I hate these dredges of society. I don't even own a business or have anything to do with Google+.
These bags of crap masquerade their phone number to spoof the called from name.
Always, always, always file a complaint at www.fcc.gov/complaints
When they take these scumbags to court (and they often do), they force them to payout to those that they have called.
After filing with the FCC you will automatically be on the class action lawsuit.
Use your correct address as they will notify you when the trial starts.
To date I have received $1500 twice from 2 different telemarketers.
