North Star Capital Acquisition Zenith Acquisition Corp. Who Are They? How Did They Become "Current Creditors"? Amherst , New York

I live in California, and I just received a letter from a collection agency named Superlative Receivables Management claiming that they are attempting to collect a debt for my "Current Creditor" North Star Capital Acquisition, and showing a company that I have never heard of as the "Original Creditor". I received a letter from a company named Accounts Receivable Management, Inc. about 10 months ago saying the same thing, and disputed it in writing.

I have never heard of North Star Capital Acquisition, never did any business with them or the stated original creditor, and do not know why they are saying that I owe them money or how they are a "Current Creditor". I will respond to that effect in writing to Superlative Receivables Management, just as I did with Accounts Receivables Management.

Is North Star Capital Acquisitions also doing business as Zenith Acquisition Corp? I think I saw that name on one of my credit reports last year, along with their supposed client's name, and was not able to figure out what the item was. Whatever it is, it has a "Date of 1st Delinquency" of November, 2006, so it's pretty old.

Not sure what to do about this, other than continue to dispute it, as it is not my debt.
