Another Month Another "Payment Site Not Working" Message!

As the title said, Another month, Another "Payment Site Not Working" message!

Your payment site has been not working for the last three days. Yes, I've cleared my cache, cookies, restarted my modem and router. Secret, I'm an engineer with extensive networking experience, so PLEASE lets skip the solutions on your screen!

My bill is due tomorrow, so how can I pay it?

Second issue, I moved and transferred my internet service last April. Xfinity billing is still showing the account at my previous address!

Thanks Gene
