Delta Dental Refuses to Reimburse Claims, Gives Me The Runaround Via Telephone Glen Allen Virginia

I received Dental Care on August 20.  I have yet to be reimbursed for this service, on 1/10/2013.
I have called Delta Dental 4 times now regarding this - they tell me that they will reissue the check that I never received, and that it may take up to 4 to 6 weeks.

 I wait, one month goes by, then two months, and no check.  Every time I call back, the cycle repeats - their customer service is also terrible, and it is consistently difficult to speak to an actual representative.  They go so far as to actually automatically hang up on you if you do not select one of their menu options, but instead press "0" to try to get through.

Delta Dental is the worst dental insurance I have yet to experience, but since they are provided through my employer, they feel no need to actually provide me with good service, as I am not free to leave the service.  

Do yourself a favor and avoid this insurance company if you can - they are scam artists, and they have kept my money and actually lied to me several times about the check that they owe me.  Dental care is expensive enough WITH insurance, much less with an insurance company who profits off of your individual losses, and then refuses to progress your claim.   Unacceptable.
