Called me here in BC a few minutes ago. If the name is "unknown", and I do not recognize the number, I never answer and always block that number. If it was a genuine call, a message would have been left.
Accented chap asked if I had a mortgage, I asked why he asked, he said he was from the mortgage company and did I have a mortgage, when I went silent he hung up.
A man with a heavy accent identified that he wanted to conduct and that he was called from Oakville, Ontario. He said that it was a quick survey about lifestyle. After 2 question, our family income came up and I hung up. He called back to excuse the poor connection and I responded with...You said you were calling from Oakville, but 902 area code is in the Maritimes. He quickly hung up.
