You should always verify you are on a correct domain before you send BTC anywhere.
In case of Blender, the domains are:
https://bitblender.io ~ Clearnet, purely informative, no BTC addresses shown there, no mixing happening.
http://bitblendervrfkzr.onion ~ The actual mixer, this is the only valid domain to mix coins via using Bitcoin Blender.
Yes, you have fallen for an impersonator site, a fake domain that is pretending to be Blender, but has nothing to do with the service.
You have been scammed.

The same applies to you. Bitblender has no .me domain.
