Did a survey for Japan, got the $5.00 as promised-----took about 40 minutes, was told it would be 15 minutes.
Did a political survey, was promised $5.00, got $4.00 instead.

All the other surveys that promised $0.25 or $0.50 partial credit, received $0.00 for all.

E-Rewards tweaked their system to go directly to "another survey offer", claiming they are giving partial credit at the same time.

They have not been giving partial credit. It must be the usual evil Marc Zuckerberg "hide the error" mentality at E-Rewards, I suppose.
