Tens of people have access to our phones well hundreds really.
Then it’s certainly understandable that you wouldn’t be able to track who called, but how is the one returning the call supposed to know that, for you to call them a moron?
From the other perspective, I’ve returned calls, not knowing whom I was calling, and finding out that it was an institution with many phone lines, but one number, such as yours. It’s very frustrating on my end not to be able to know who called – and at times it turned out that it was indeed an important call.
