Getting Frustrated

I sent an email to the Human Resources office in Cedar Rapids today. Up till now I have left at least four messages (with live people) and one email for the local HR, Emily Porter, to call me with answers to the questions I have with no response.

I need to know how long I am covered on dental because I have two teeth that need crowns. I had to wait until I was with Delta Dental one year before having them done. That will be up February 3. My last check will be cut February 16. Will I have time to get the work approved and done????? Halfmoon
