Bad service and incorrect pricing

Had the worse experience now with a call centre lady.i installed 2 decoders at my house, one explora and one normal HD decoder. I qualified for pvr discount since I have extra view ,she was was adamant on not providing a discount and had to wait 24 hours to 48 hours because they haven't received payment and they have to wait for there finance department, I payed them for the months pro-rata rates.this is the forth time calling them and still they are clueless what's going on. She also did not want me to speak to her manager.
