Appalling customer service

I have been trying for a week to get a confirmation of membership from Momentum Health, first through my broker, then directly. Every time they send me the document it has a line that says the policy end date was in 2015. The policy is and has been in force since 2013. I don't understand why there's an end date on this in the first place. It makes it look like it's for a policy that was cancelled five years ago.
