Disabled and Xfinity won't let me pay my bill

I appreciate that information. It specifically says I can pay by entering my information into the system on the phone but when I call it's not letting me get to the billing section as described. Then it tells me it can't help me and hangs up.

It won't let me pay online. The Xfinity Assistant won't connect me to an agent unless I ask about services I don't even have (or want). I was supposed to get connected to the IVR payment system on the phone but the robot keeps telling me she can't access my payment method without any prompt to put in a new one and then hangs up on me. I just want to pay my bill. 

Thank you for responding but I have spent hours with customer service at this point and have gotten nowhere. I have been told my account is blocked - without explanation as to why - just that the system blocked it - and they want me to go in person to a store. I cannot leave my apartment and I have medical documentation explaining I have become disabled. I don't have someone to go for me. I have tried paying on the app and in the browser, both on my phone and online, cleared cookies, changed passwords - everything imaginable.

Xfinity needs to unblock my account so I can pay online or let me give my gift card information over the phone. The automated system says "you can make a make a payment or enroll in autopay" and then says "I wasn't able to retrieve your payment information at this time" and hangs up on me.

I was told to call back on the due date (Saturday) and that a manager can take my payment information over the phone. I don't know why I wasn't just put in touch with a manager to begin with if that's the case. I am paying with several gift cards I earned through game testing online - I paid the same way last month without problem.

Can you unblock my account?
