Wow, bad luck right there, man.
What exactly is the chance of defrost, because I've always wondered about that...
Usually I get defrosted on the first or second turn, but one time...
I forget exactly which Pokemon it was, but one Pokemon of mine was up against a Milotic that scored a freeze on me, and then died to Toxic. Then the opponent sent out a Shuckle, which killed me through a mix of Sandstorm and Wrap over about 20 turns, while I was helpless, frozen. I never defrosted.
The Battle Tower is a neverending source of bad luck for me. I usually get about 50-60 wins and then go down to a battle that goes something like this:
ch freeze blizzard ch defrost refrozen defrost miss ch pokemon dies, then CH para T-bolt fully paralyzed fully paralyzed miss fully paralyzed pokemon dies, and then sheer cold hits game over
