I sent btc from my wallet to my web site balance, deposit never showed I have had hundreds of confirmations but the funding never made it from my wallet to the balance I was maintaining on a Web site (Alhabay). On blockchain the transaction is listed as "unspent." Where did my funds go? Can I get them back? I've been trying with zero success to get help from Alphabay.

Thank you.
You will need to contact the site, Alhabay, for support. This is your only way. The bitcoins have been sent and confirmed on the blockchain, and they are in Alhabay's possession right now. 

Bitcoin is like cash. It's irreversible. Once you've gave someone cash, they have it and the only way you can get it back is if they give it back to you.
