The power of telephone customer service

Even in today's modern world, telephone/voice is still the most preferred customer service channel. When things get urgent or complicated, customers simply want to pick up the phone and speak to a person of flesh and blood.

Turn customers into fans

A 1-on-1 voice call allows customers to more effectively express their emotions and to be heard compared to digital channels. It enables them to have a real human connection instead of a digital one. If you get it right, this can make all the difference between becoming a fan of your brand or a fan of your biggest competitor.
