No, you do not refile.
You can phone the IRS Taxpayer Advocate Service and see if they can assist you with this. Explain to them what all has happened with the IRS receiving your documents then sending you the IRS letter that they were going to review it, and the difficulty you are having in getting any information or results from the IRS. Mention that you have already talked to the IRS a couple of times.
At the following IRS website, find the USA map and click on your state, and it will give you the number of your IRS Taxpayer Advocate.
