No response to 221g is VISA refusal?

A small query I have in the DS-160 form that I’m filling.

It asks “Have you ever been refused a U.S. Visa” and the answer may be yes or no because in the year 2007 I received 221g query for submitting documents like “market analysis report”.
I didn’t submit the documents then as the employer didn’t get back and my case may have been abandoned due to no response. Petition is also expired.

In such case should I treat this as refusal of visa? But I didn’t receive any refusal letter either…
