Rewardport.com Reward Port, Inc Wanted to redeem $25 Walmart gift card. After waiting 9 mos.card stills shows "pending" in my account. Cherry Hill, New Jersey

I have been a member of Rewards Port surveys for some time now.  Back in January of this year I requested a $25 WalMart gift card for which I was redeeming the required points.  I have written to Rewards Port at least a dozen or more times. (copies of most of these e-mails are available upon request) My account still shows this redemption as pending.  My last several attempts to contact the company have been completely ignored. I strongly believe that 9 months is an unreasonable amount of time for this transaction.  I cannot find a phone number ,but the physical address for this company is as follows:  Rewardport, INC, 1949, Route 70 E., Suite 7, Cherry Hill, NJ  08003.  The customer service web address is: support@rewardport.com.  
Repeated e-mails to this address from me have gone unanswered since about the first six or so.  I would really like to have what I have earned
