I've also been affected by both of these brokers. Optionrally still haven't paid me my EUR 200 since last September and Scala just returned my deposit of EUR 250 upon asking for a withdrawal of EUR 850. Now there's little more of virtual money on my account, but they don't reply on my e-mails, I can't reach them over the phone.
Regarding link to both of these brokers, I can add that there was an agent called Jason Lockheart who replied me on skype, but when I started asking him about my missing withdrawals, he blocked me. And he had 2 e-mail addresses ending with .scalatrade.com and .optionrally.com. I know it's nothing, but still.
