Trying to remove a channel. No costumer service?

So I'm trying to remove the HBO max subscription from my account. And it shouldn't be that difficult , but there's a wifi outage in my area today. I figured be no problem just using my mobile data and checking Checking my billing details and just removing the charge. Somehow they've made this virtually IMPOSSIBLE do to from your cell phone, everything I try to check my channels and remove that charge it tells me I need to call in, okay no problem, I go to call, and the automated robot hangs up after telling about my outage. This make 0 sense why am I not able to talk to customer support about my TV CHANNELS because there is no wifi? Then  the Chat robot also cannot edit my channels because of the outage? Why can't to discuss options for billing due to wifi? And the moblie data I'm using which Is also XFINITY MOBLIE does work well either. Literally spending 10 minutes to load a single web age HOPING it'll let me edit my billing details. Then I tried to call my local store to help me out, and even the locals store phone number goes straight to the same robot, and hangs up instantly after texting me updates to the outage. This is ridiculous not to mention this is already the 4th outage this month and we are only 20 days in! I didn't even want to start a "forum" I just wanted to submit a support ticket, which again xfinity doesn't have anywhere to submit support tickets unless it's for a monetary reason aka refund or mispayment. It's ridiculous that I can't call to have my hbx max subscription removed. I'm being charged again and again for something i dont use. just because they won't let me remove it from my account!
