Hi!
I so understand your frustration! It happened to me once during the process, but they CALLED me and asked why I hadn't returned the forms they sent. I said, "WHAT forms?????" So, they resent them and it was NO problem.
I would call again and ask to speak to a supervisor. One thing I have found out when talking to just any rep is that they often don't know what they are talking about. Explain to a supervisor and then ask what they can do to reinstate you. Tell the person they NEVER called you, and ask why they didn't follow up. I KNOW they know that this happens sometimes, so why they didn't call baffles me. If they can't reinstate you, ask if you should refile. I have never heard of going to a hearing because they didn't receive paperwork. Hope this helps.
