It seems you were a victim of a phishing site. If you had thought that you are using bitcoin blender than you are mistaken from the beggining; Bitcoin-blender is a Tor-hidden service that uses smart technology to mix bitcoins. As set in the signature of user blender there is only two links:
https://bitblender.io/ : an awsome guide on what is bitcoin-blender and how to start with it using Tor.
http://bitblendervrfkzr.onion : this is the official bitcoin blender Tor URL

Am sorry.
You should always be careful!
