I saw that user MrWhiteBites managed to withdraw his 1.5 btc which Hitbtc had frozen, and he is open to receiving PMs from someone with the same problem. You can contact him, maybe you will get a hint.
I think you should try again as you already sent them KYC as a recovery effort, even if it get rejected doesn't mean your ID will be deleted.

But wait, I'm confused how much of your funds were frozen, is it 0.01 btc, only $70 or the accumulation of both?
