I would like to know why I did not receive my $1000 Walmart gift card and my Apple Ipod # please help me Thank You Pam

To PCH I went thru with the survey for 2 Walmart gift card and until today I have received nothing it was 100 Walmart gift card and a 1000 Walmart gift card please find out what happened to my gift card and I also did a survey for an Apple Ipod 3 and never received that either. Please look into this, because I am not doing any more survey's until I find out why I am not receiving my gifts. Thank You Pam
