Freebitco has been going downhill for over a year now and things are obviously getting worse. There are so many users like you who also have their withdrawal pending for a long time, some of them eventually get processed, so let us hope yours gets processed eventually.
I request Freebitco.in support team to respond here publicly and resolve this issue immediately.
I'm afraid, their representatives (TheQuin and CSFBC) are no longer active in the forum, so they are not going to respond here.
If unresolved, this case will be considered as a scam warning for other users.
This is a thread that covers the fall of Freebitco, you can even see that users still post complaints in that topic.
