That is incorrect. You're supposed to send a valid notice to the registered DMCA agent. Here's the sort of ruling you get when you send out defective notices:

"In Perfect 10, Inc. v. CCBill LLC, the Ninth Circuit held that the properly constructed notice must exist in one communication.[16] A copyright owner cannot “cobble together adequate notice from separately defective notices” because that would unduly burden the OSP."

Miscommunications happen. Its a fact of life and its even moreso when you're dealing with a complex legal matter. I'm offering up my time as an unpaid ex-employee to help someone out who seems to be having difficulty. The offer stands to others but not indefinitely because as time passes, I'll know less and less people who work at the company.
