This number is the direct number for the accounts department. 1-800-829-0922. Tell the agent that you are inquiring about the status of your refund and want to know where it is in the process. If in the event that they are auditing you, find out what type of documentation they need from you in order to complete the processing of the tax return. If they say that your return is "in process" or otherwise do not want to speak with you, then demand to speak with a supervisor. In my experience, the agents in the accounts department are usually pretty helpful.
