I agree with Eric, Ron, and Cindy, but, again, as others have pointed out, this depends on your contract. I am not clear in my own mind what sort of contract or contracts you had with this agent. You pose your question as a "home buyer in 22032", yet your question implies that you are a home seller. Are you both? Did you have two different contracts, one to buy a home and one to sell your current home, with the same agent/broker? Did you have one contract to do both? In that latter case, this is a non-standard contract, and you need to both seek out your agent' managing broker and, if I were in your shoes, seek an attorney immediately.
In any case, if the agent is not also the managing broker of the office from which he works ( you can contact the Virginia Real Estate Board to find out if this is the case ), then you need to go to the managing broker of the agent's office first. If the situation in which you find yourself is not resolved to your satisfaction, then, I would Google search Martindale-Hubble and seek an attorney on their Web site with a real estate specialty in your area who is highly recommended by peers. Before engaging that attorney, I would ask the attorney whether or not he has any conflicts of interest with the agent, his firm, and brokers thereof.
