PrizeRebel not getting credited on some why?

Question

Ok well Anyways i just got 8 credited points and got Xbox 360 1 month Membership but the problem is some surveys dont give me my credits liek the ones that say

Description: Submit your valid email

Requirement:US Residents Only

All it saying to do is sumbit your vaild e-mail and im still not getting credited whats going on

Answer 1

Sometimes, these surveys are from a single site, so if you already gave your info on one of their sites, you won't get credited anymore... Unless you make a bunch of dummy e-mail addresses
