bad service and lying consultants

I wanted to fill in my tooth instead I had to pull it out because my Active plan doesn't cover that. okay that I understand, what made me angry was the fact that I have savings benefit account with them but I was told it wont cover that, how ? isn't my money in it ? I sent an email asking but they told me it covers 100% of all dental services but when my dentist called they said it doesn't. Please balance me here what is what ?
