hey, is that what they told you on the phone or through a letter? When I ran out of my 2nd extension, I also had some problems getting the 3rd setup, but I did end up receiving it after some time. What I had to to do was call them a bunch of times to reach someone who could actually help me. I was told to re-file online for a new unemployment claim and once the system recognized that I had been out of work, that I would be eligible for the third claim. My 3rd extension was not "automatically filed" like I was told it would. After I filed for a new claim, which I was denied since I had not been working... the system then recognized I should be setup for the 3rd extension.. I then received my claim forms.
if i were you I would call them again and try to see whats up.. you can also email them through their website and ask a question (i tried that once and it worked too). i know that their policies change and that the old method i used may not work..
hope it works out for you..
