How do I cancel my Internet service? Service has been constantly out. I chose not to bother with payment last month because of how often it was out and this month Comcast has been nearly constantly out in my area anyway. I've not had service this month because of unpaid past due and yet just received another bill for this month despite having internet for 0% of the month. My bill has already gone up despite usage having gone down (I don't WANT more allowance per month because I don't USE more) and I'm fed up with the entire company. Comcast and Xfinity are a scam that don't provide the services that customers pay for and don't compensate the customers their payment for services not received.
