With on-hold, it’s not just about upselling other services, although that is important. You can use the time a customer is on hold to educate them more about your business and about your industry.

Corporate cost-cutting and new technology have resulted in the advent of automated systems that can make the on-hold experience even more frustrating. It can feel near-impossible to get a human on the phone these days, which a national survey conducted by Consumer Reports found to be Americans' second-greatest annoyance, after hidden fees but beating out inaccurate weather reports and dog poop.
