Xfinity support

Internet went out abruptly this afternoon while working from home. Had 5 video conferences scheduled following the outage that I had to take from my phone. Needless to say, there was a significant loss in production for 2 people living / working remotely as a result. Called customer support twice with absolutely zero assistance provided. Spoke to a person who sounded like a chatbot. Absolutely no solution or troubleshooting available and only option was to schedule live tech support — WITH THE ONLY WINDOW AVAILABLE 6 DAYS FROM NOW!! This is completely unacceptable. I pay far too much for internet to have uncertainty introduced into my career as a work from home employee. Honestly not sure if I can continue service with Xfinity and am likely to switch carriers if not addressed immediately.,
