I received letter 4883c which instructions to call [phone number removed] to verify my identity. I must call within 30 days or my return will not be processed. But every time I trying calling, I listen to a long recorded message before it says that they have reached capacity and cannot answer my call, please call back later today or another day. But I've called at least 5 times now and it never goes through. Any ideas on what I should do? Thanks.
