Mortgage and Insurance

My husband worked for a small business (incorporated) that ran out of money last year and laid all of its employees off, including him, although he may be rehired if/when the business recovers.  He had a business credit card through Capital One.  The business he worked for was a corporation and he was one of the shareholders of the corporation but there were other, bigger investors in the corporation.  After the business ran out of money last summer, the credit card was not paid for about five months.  But when the business started to get back on its feet in December and got paid by some of its customers who had been late on their accounts, the business then paid the credit card account in full.  The account is now showing up on his personal credit report as having been 120 days past due.  Is there any way to get this corrected?  When he called Capital One, they told him that he was personally liable on the account as well, but that was not what he understood (and the whole balance on the account was business-related charges — in other words, he never used it for anything personal).  Capital One did call him last fall, but he thought it was the business’s  problem so he didn’t do anything about it other than telling their accountant that Capital One had called. I guess they dropped the ball because they weren’t sure the business would survive.  But the business has now paid off the account, in full.  But Capital One says they will not remove it from my husband’s report.  Any suggestions???  Would it help to have the business’s lawyer call?
