Be very careful of your dealings with bitmixer.io

"I don't take kindly to your accusations that I transferred the btcs.

I have no idea what your service is capable of - and exposing and utilizing ones private keys does not seem out the question now - considering how you handled this situation.
 
You have done nothing but make accusations since I inquired about the matter.

Instead of taking down facts and investigating you've only wanted to quickly point fingers at me.

I had to chase down the address where my btc are and even then I repeatedly had to ask you is that address connected to your service.

I will not stop investigating what happened to my coins nor alerting other people to you shoddy customer service and service in general."
