Hard to navigate to pay bills online.

Hard to navigate to pay bills online.

Suddenly my bill shot up to $600! Called, they were supposed to send me a link for a Zoom conference to resolve this issue. Never received a link, a call or am email. They keep telling me that the water ran through my pipes. How? I have no leaks, no dripping faucets, nothing changed. Sigh. This is too random. I have lived here 20 years and never had such a high bill.
