Management sent my deposit itemization on day 32. NC law says 30 days. Does this matter?

I moved out June 1st. Got the itemized deposit letter on July 3rd, that's 32 days. NC G.S. 42-52 requires return of the deposit or itemization within 30 days. They're trying to keep $890. Is the 2-day delay enough to void their ability to withhold? Has anyone actually used this successfully?
