Medefield review: Instead of $35 I got $10 voucher 1

I saw the ad about the surveys and contacted Medefield. I filled couple of the surveys and wanted to stop, but their customer services sent me the email. They offered to fill the surveys within one month and they would pay me $35. It was easy money and I agreed. I filled a lot of surveys and waited for the payment, but the customer services sent me fake voucher for $10. Don’t waste your time.
