I've never had any problems the past 4 years. Always easy to enroll and representatives friendly and knowledgeable. Always got affordable plan and eligible for decent tax credit. However, this year was terrible. Was put in wrong plan, then when they admitted it was their mistake, they allowed me to switch to correct plan, but expected me to pay the payments for past 4 months I was in wrong plan. I was told there was nothing they could do and told to file an appeal which I did, only to be told they couldn't approve my appeal request. Then, another representative was very nice and went above and beyond to fix it beings was their mistake, so either they are very helpful, or completely useless, depending who you talk to and if you're persistent.
