I was trying to renew my plan for two weeks and every time I call they say they cannot help me. They refuse to answer any questions. The only thing they say is go online. Online it dose not have the dentist I currently go to listed under the plan that I currently have and and trying to renew. Not sure what's going on at this place but they should be there to help customers.
