Verizon Business website Page unavailable

I have been trying to access Verizon’s business website to view and pay my employer’s bill for over 6 weeks. I receive a Page is unavailable error. I have tried clearing cache, history, cookies etc multiple times. I have tried both Chrome and Edge browsers. I have tried at work, at home, on my phone, different computers and nothing works. What do I need to do to access the business website?
