Internet is down since morning and no updates from Xfinity

It is night time and the Internet is down since Morning. Xfinity keeps on messaging that it will be restored but, it did not and neither they are telling when it will be restored. Xfinity chat is nothing but a bot keeps running the loop saying I will be informed when the internet is restored with no further information. Is there any reliable point of contact email or number to know what is going on here? It is absolutely frustrating when you pay so high for internet connectivity and the service provider kicks you out when you are just trying to know the realistic timeline to get problem resolved so that we can plan at least something. Totally unprofessional!
