Redeng, I did the same Peeps on PL, and I didn't get credit either!!! It looks promising at first (Peeps) - but I noticed that you have to get through a few months, hurdles, and get about 15 referrals to be able to claim a reward!! Not worth the hassle IMO.
Payment wall credited me for the survey probably after about 1 hour????
PS: nice to see some surveys finally!!!!!
