Mystery Calls

Call centres are essential contact points between your customers and your company. They contribute greatly to customer loyalty. Using our experienced Mystery Callers, we conduct intensive quality monitoring. With the aid of a customised evaluation scheme, we establish a development analysis of your employees. Your customer communication can thus be systematically improved.


We recommend also monitoring your call centre by seeding addresses via Mystery Calls and continually-monitored phone numbers.
