Tech support - you make it impossible to pay bill!

I've been trying and tyrying to pay my bill for days now.  For reasons I will NOT go into there, I cannot use your robotic method on the phone.  I've been trying to pay online but keep getting 404 Bad Gateway.  No human will answer any phone no matter what I say or do.  Multiple times your Robot (phone0 has said they will connect me, then hans up.  FOR DAYS!!!  I am elderly and disabled - sometimes I cannot even use my phone (bars unreliable and so it will use WIFI) without the wifi.  

As I said, this has been going on FOR DAYS and now I get a message that 30ish dollars are overdue and i may be cut off.  WHY IS THIS HAPPENING??!!  Please help me!  How can I get someone to CALL me?? A robot will not do.
