LEGACY L D INTL, INC I received a bill for 2 zero dialing calls for 6 min each amount billed $46.71 I called them they won't do anything about it. CYPRESS California

I accepted 2 zero dial calls from a Correctional Facility in Los Angeles, CA.  The first call lasted 6 minutes and the second call lasted 7 minutes.  I got a bill for $46.71 which I believe is an outrageous amount for two calls  that didn't last too long.  I called Legacy LD Intl, Inc.  I asked them if they can lower the charges because that was too much what they were charging for the 2 calls.  They said no, they couldn't do anything about it.  They don't care what other companies charge.
