I only found one topic on the forum about this from a year and a half ago, and I don't know how familiar people are with this service.
There is a great captcha solver called
Rumola
that works as an extension/add-on for Chrome, Firefox, and Safari. I have used this for quite some time and thought it was abandoned, but I re-enabled the extension for Chrome, and it works perfectly for me. Do give this a try if you haven't.
You are granted 5 free credits (1 credit per successful captcha), and then you are required to purchase more. Setup is easy to navigate through. Good luck!
