I am in the last month of the federal COBRA coverage being managed by Conexis. They have arbitrarily changed my premium rate based on information provided in error by my former employer, who has recognized the error and has tried to change the mistake. Instead, Conexis is charging my former employee an extra $500 and trying to state that I owe $300 from September 2010 which they acknowledged they didn't bill me for. Now, two days before Christmas, they are demanding by "word of mouth" and "email" that I pay this extra $300 without an explanation for the change. They have floated a couple of random numbers without explanation. If I don't pay, they will cancel the remaining 10 days I have left, thereby threatening the Cal-Cobra I am now eligible for. I thought Conexis was indulging in unfair business practices when this first uneasy relationship began in August/September of 2009. They informed me I had no coverage going back at least 45 days and demanded I pay 2-3 months "back premiums" to show that I had had continuous coverage without actually having the benefits available. They said that they didn't benefit anything, that was just the way the system worked. Now, they are utilizing strong arm tactics at the last minute demanding I pay an extra $300, without question or adequate notice, or they will cut off my benefits and threaten my continuing benefits with Cal-Cobra. Where is California's insurance commissioner and why isn't he investigating Conexis for unfair business practices against California's struggling unemployed?
