The dark ages of customer service aren't so very far behind us. Let's never forget the horrors of only being able to contact your product or service provider on the phone – and only during office hours. And then finding the customer service number engaged for an hour or more. And then waiting on hold for 20 minutes, listening to music that no one should ever have to listen to, only to be put through to the wrong person, who then unwittingly hangs up as they try to transfer you.
