Did you try haggling with them at all? They gave me free installation 2 years ago because i was a new customer and then they kept cancelling my installations or sending incompetent installers so I had multiple visits and they tried to charge me. I refused to pay and told them that it was their own fault and they actually ended up giving me like 50 bucks or something.
Then when we upgraded from regular to HD we paid like $185 for installation and equipment but we got a rebate for the full amount. Try and call back again and see if you can work something out. Never hurts to ask for the representative’s manager too. Good luck.
