It would be less confusing if it was All Calls, then all unique calls, then the breakdown of one-time and repeat callers...so you'd more clearly see that one time + repeat = all unique calls. The way it is now, dealers aren't seeing that they have much of an issue. They see that they had 50 repeat calls but they won't remember that it's 1 caller that could have called 10 times or 100 times.
We understand the confusion that the difference between Callers and Calls on the ServiceVision dashboard can cause. We are not going to rename Repeat Callers, however. Instead, we are planning to redesign the dashboard to resolve this issue as well as others for the next major release of ServiceVision.
