if you have an email or some written correspondence from the agent(s) i would suggest contacting the sales manager for your agents firm and let them know it was never attended to. This will get you some response from the agent.
hope this gets resolved for you.
Another strategy would be to review your contracts and see how the repairs were written in. If you notice they were written in your contract, and you still don't have a response from either agent, you could contact escrow directly to find out about the funds. At times, issues such as this are overlooked by the escrow officer and could have accidently been credited to the seller. Your final "HUD", or settlement statement will specifically state where all monies were disbursed. As with all transactions, it's not wise or legal in most states to settle monies "outside" of escrow.
If this is not the case, and you have "written" documentation of stated repair issue being paid by the seller, you could go directly to "both" broker's of the agent to resolve and receive guidance on the monies.
Without seeing or knowing the exact paper trail on such negotiations, it's hard to determine the exact solution. As stated previously, a consultation with a RE attorney may be required to settle this situation.
Best of luck!

If this $500 repair clause was written into your contract then it should hav been given to you at the closing. Make sure that you have all the documentation regarding this issue and first discuss it with your agent's Broker (his boss so to speak). If they cannot resolve this for you then you should consult an attorney about filing a claim in small claims court.
I hope this is helpful.
Good luck to you!
