Relocation Charges - DirecTV

I was told by a customer service representative that my relocation charge would be lowered to $100 versus $150 because there was already a dish installed at the relocation residence. When my bill came the charge was $150. After multiple phone calls to resolve nobody was able to help or even consider lowering the charge. I am disappointed needless to say and would like to know why this reduced charge was not followed through with.

This question, "Relocation Charges," is about DirecTV channels, programming, equipment, and sports.
