Harris Poll Online Will not reward me my hard earned points Internet

I have been a member of Harris Poll Online for several years.  I have been trying to cash in some of my well earned points, for over a month.  I fill out the form for a reward, for which I chose an Amazon Gift Card.  When I submit the form, I get a message saying that my date of birth doesn't match their records.  After that, I send them an e-mail, asking them to help me clear it up.  Their reply asks me for several other aspects of my profile, which I promptly reply to, with answers.  After that, I don't hear from them, until I start the whole process, again.  As I said, this back & forth stalling has been going on for over a month.  I'm am beyond frustrated!!!  I called their phone number, & always get the message that the operator is not there.  I need help!
