Fastest Rewards - SLOW REWARDS!

Another quick note of caution. I may have to revise my recommendation of the site Fastest Rewards. Twice now have I tired to cash out and not received anything for 72 hours despite the site saying it takes 24 hours to receive payment. Both times I've emailed and chased and to their credit, have received a response and then the amount has been credited. But I wonder what would happen if I didn't chase? next time I'll try and see how long it takes, if it comes through at all.....
