Humana Insurance Called to get an estimate for dental service and agents completely refused to route me to a supervisor after repeatedly requests. LOUISVILLE KY

I am a disabled veteran and have Humana Dental Preferred Insurance. The insurance is obtained via the local federal union and is authorized by Benefits Architects Inc.
 
 On July 7, 2021 at approximately 09:39 a.m. I called Humana Dental Services at (800) 233-4013 in reference to obtaining information about dental costs. The conversation was for eleven minutes before being placed on hold for an extended period of time after requesting to speak to a supervisor.
 
The representative  kept stalling on the line and refused the request before hunging-up the phone. Therefore, I called back and spoke with another representative. The representative identified herself as Agent Log In AEC3673. From the onset of the phone conversation I provided her the requested information.  
 
Once again, the same tacts was used as I explained on a fifth-grade level for her to comperhend. However, due to her language she still could not understand ENGLISH fully. It seems as if Humana has employed over seas cheap labor but bill the HELL OUT OF AMERICANS!
 
The individual refused to route me to a supervisor after I requested several times. She continued to put me on hold and insisted that I provide her additional information although she had been given the data. As expected when gatekeepers for the spin doctors do not know an answer they will either hang-up or pretend they do not understand first grade ENGLISH.
 
This has been an ongoing issue that Humana first line contact individuals refuse requests to speak with a supervisor directly. Humana has no problem debiting my account bimonthly for insurance costs but refuses to route calls for dental questions.
