e-Rewards review: Survey site that suspends accounts and earnings can't be redeemed

Been a member of e-rewards site for 10 years and currently have Diamond status.
I had $593 I had accumulated, spending countless hours earning them and I am not able to redeem any.
No longer provided survey's on the e-rewards site, I contacted customer support and was informed my account was suspended.
Being 100% compliant with e-rewards 'Terms & Conditions', I asked for details and all I got was another boilerplate response.
I have e-mailed countless times. There is no phone number to contact the company.
I see this has happened to countless people since last year.
If you have an account, redeem your rewards immediately. I would not use this company. Terrible business practice.
