Cancel *only* mobile service

Hi,

I am crossposting this from the mobile forum because the customer service process is as much of an issue here as the inability to cancel issue, itself. The question is how to cancel only the mobile service, not internet, as the app, the website, the chat, the phone number and the mobile forum do not include any indication of how to do this for my particular scenario and beyond a certain point it looks like intentional obfuscation with the intention of keeping users locked in a service they don't want.

Thanks
