Need to cancel mobile and TV services

I haven't been able to get through the customer service line and have experienced difficulties with the line disconnecting, so I'm going to try to cancel two services here.

I need to cancel the TV service and mobile service, but keep the Internet service.  I have no complaints with the Internet service, but I have literally never used my TV and despite having relayed this to Xfinity multiple times in the past, I keep getting billed for TV services.  I thought about moving to mobile, but right now that's not something I want to deal with so I'm looking to cancel that as well.  Xfinity recently sent me new equipment I didn't ask for.  I don't even know how many devices I need to return since Xfinity has historically sent me random equipment that I have never used despite indicating I want to cancel the TV service.  I generally don't want to spend time fighting with customer service about cancelling services and the price was feasible enough I let it go, but now that my bill is jumping upwards of $200 per month, that's just not sustainable.  I should not be paying $200 for the Internet only.
