The Panel Station — Amazon Reward Voucher pending since a long while.

You have worst Complaint Resolution System in all over world. You do not give any response to any complaint or any mail of your panelists. What is the method? Is there any cost for our time and hard work? Since when is my Amazon Reward Voucher pending, which I redeem on 16 March, but till now you have not clear nor do you give any response to my mail. How many of my complaints are pending with you, but you have not resolved any of them. Whenever we complete a survey for you, then 80 times out of 100 it does not reach the reward page, and if we complain or mail you, then it does not get any response. You have made a joke You tell me, is this kind of attitude of an honest company? Please be honest with your panelists. Clear my reward voucher and resolve my other complaints as well.
Thanks.
