This company called yesterday but it was unknown name and private number so it got past me. We ARE running a business here and unfortunately can't ignore everything. Tried to say our two-year online listing needed to be renewed. Said they'd email the renewal info but nothing arrived.
Today the big cheese called, with a number and "Benchmark" displayed. He took offence that I called him a scam. Google connects them to 411.ca, a proven scam which has called dozens of times since I started tracking three years ago.
