Which companies would be subject to such regulation? For instance, a startup without an established customer support center would be fined and forced to shut down because of those fines or because of the money spent on customer center ? What would be the kpi for customer service? Time spent on the wait line? Customer ratings?! Business days before an email reply? What if someone malicious starts DDoS me with fake customer service requests just to make me unable to deliver an "acceptable standard of customer support service"?
