Delta Dental Delta Dental of New York Delta Dental did not sign me up the plan that I paid for, when it does, it's the WRONG pplan Nationwide

I signed up to Delta dental PPO plan under the New York State of Health website back in Feb 10, 2014, for the coverage to be effective on April 1, 2014. However, I was NEVER enrolled until August, 2014. When I was finally enrolled. Delta Dental enrolled me to the HMO plan, instead of a PPO plan. The only reason why I paid for the PPO plan is my dentist only accept PPO, but NOT HMO. An agent from Delta Dental was the contact that I got from NYState of Health, who has been helping me on this. But does not seems to go anywhere. I need to get this resolved, this is extremely unacceptable and infuriating that it's been more than 5 months since I'm technically enrolled and be covered by insurance.  Delta Dental needs to get the act together.
