What are the new phone support options for Coinbase one?

I've been hearing about Coinbase One's expanding customer support features. Could you elaborate on the new phone support options they've introduced? Specifically, I'm curious about the availability of toll-free numbers, extended hours of operation, or any dedicated support lines for specific issues like account verification or transaction disputes. Additionally, how do these new phone support options integrate with their existing online support channels? I'd appreciate a comprehensive overview of the enhancements Coinbase One has made to enhance the customer experience through phone support.
