UPDATE: After speaking with the Attorney General's Office on the phone, by some "miracle" One Poll suddenly unlocked my account again. However, still not seeing any surveys available. We will see what happens.
But, I did learn that it is indeed highly illegal (in some cases a felony) for any survey company to withold money previously earned from them, despite their TOS. Typically the Consumer Fraud Dept within the Attorney General's Office for the state the survey site is located in handles these cases and they do take criminal action against these companies, especially when numerous complaints are received against them. Therefore never be afraid to report a company for witholding money earned.
