Cassandra Gekas, operations director for Vermont Health Connect, said staff members are working on a problem in which hundreds of people who paid their monthly premiums on time were canceled for nonpayment. Apparently, the cancellations were related to a five- to seven-day period it takes for the system to process end of the month payments. Vermont Health Connect was plagued with technical glitches and security problems after its launch Oct. 1, 2013.
