"MyServices" at timewarnercable.com provides some detail about your subscription

The Time Warner Cable website has improved since they added the My Services feature late in 2010. If you are a Time Warner Cable subscriber you should create a user and link it to your cable subscriber number at www.timewarnercable.com. Once you have a linked account you can contact customer support via online chat which I find to be a good option. From the site click on "MyServices" and sign in to get to the "My Account" tab and from there click "View Current Services & Equipment".

Here's what is listed for me:

Current Services & Equipment

Digital Cable

• Basic Service
• Standard Service
• DVR Service
• DTV
• Hdxtra
• Converter
• HBO and Pod
• Equipment - Scientific Atlanta DVR Model #: SA8300HD (aka Cisco Explorer)

Internet

• Road Runner Online SVC
• Equipment - RCA Modem Model #: AHRCA5 (Modem User Guide PDF hosted at www.rr.com)

You can map these services and equipment to your monthly bill, but pricing specifics are not available in the My Services page nor are the individual services linked to a page offering a detailed product description or grouped in way that defines the bundle you have. For example, I know I have some sort of Double Play bundle because I have internet and TV packages (and TWC support told me so), but I don't know the specifics of the Double Play or what discounts I receive because of the flavor of Double Play I have.
