Cancel TV

I'm now 2 hours in to attempting to cancel only the TV portion of my package. I tried to "manage my plan" through the app and website but that page doesn't load. I cleared the apps cache and even turned off my phone's Wi-Fi but that page won't load. So I used the chat feature. The first rep tried getting me to sign up for other offers after I told him my bill went up $54 and I didn't y use the cable. Then our chat got disconnected. So I started a new chat. That rep tried to increase my Internet and cancel my TV. When I told him to leave my Internet the same just cancel the TV he scheduled me a call back for tomorrow. PLEASE for the love of God just cancel the TV portion of my package. If I have to go into a store just to remove cable I'm going to find another provider for Internet and Mobile. This is beyond frustrating!
