i don't agree to pay for the add ons

The place where my bill went from $70 to $101.00 a month period. It says the extra $30 is for DVR service, HD technology fee and Internet Essentials program. I don't want any of that. I don't even know how to use a DVR. I don't need HD technology. And As for the Internet, I pay $10 a month for that and I will pay that.
