The short answer is, yes - you can contact your service providers directly.
That being said, studies have shown that it generally takes an average person at least 30 minutes to negotiate a single bill on their own. It can also take additional legwork to know if you’re getting the best rates and current promotions.
This means that having several bills might take you upwards of hours to negotiate.
