I've had several issues getting the credits to apply. I have to use a different browser, deactivate ABP and it's still hit or miss if the credits work. They won't help resolve the issue and they refuse to give me the credits that I've earned. Their customer service copies and pastes the same content and it doesn't ever address the issues. I'm considering going through the BBB.
If 0/5 was an option, they would get it! I plan on sharing this information with everyone I know that uses this site!
