Cigna HealthCare Insurance Co. Cigna Health and Life Insurance Co. Changed in-network doctors without letting insured members know Chattanooga, Nationwide

We purchased an individual PPO/RPO medical insurance effective on 2/1/14.  We did thorough researched since we are VERY particular about in-network doctors.  We made sure our doctors are in the network.  We paid $1282.00 a month for a PPO (so-called PPO... the service reps repeatedly told us it is equivalent to PPO).  We paid Cigna as required.  But, Cigna changed the in-network doctors after we purchased the policy.  We, our doctors and us, didn't know Cigna removed our doctors.  We were required to pay full amount since our doctors are no longer in their list.  Cigna is soooo bad in ministering their policies.

We later found out Cigna said they removed all network doctors but 'THEY' select the doctors in their in network.  We found out no doctor in their network has American names.  It is absolutely fraud to sign someone and receive thousands of dollars but remove doctors without notifying insured persons.

I hope someone can tell me how to get this straightout.
