I would give them ZERO star if possible. I was contacted via email for a survey. THEY said they got my email from one of my banking cards. AS best I can tell, I have never given an email to ANY financial institution, except for one and they don"t issue credit cards. CMB e-mailed me at LEAST twice.
The deal was: Qualify for and take a financial services survey. I would assume that I qualified for the survey as I was able to proceed through the entire series of questions. In return for my time, I was to receive a $15 AMAZON gift card within FOUR weeks. Nothing shows up. I send an email to CMB. Their response: "Thank you for your email and interest in the survey. We have looked into this and unfortunately, it appears that you did not qualify based on your responses to our upfront screener (sic) questions. You should have seen a screen informing you of this following the (sic) those questions. OBVIOUSLY I was not shown ANY screen informing me of this. SURE, then WHY was I able to complete the 15 minute or so survey?????
