Its the first time a host blatantly refused to take any action so I was surprised by this.
Yes it's rare, usually they don't even respond.
Was the letter drafted by a lawyer, sent registered etc or was it from the court? What kind of C&D did you sent?
File DMCA with search engines, cc the email to the host so they can understand you're serious.
