Don’t make me tap the sign. YOU called US.
I can understand getting interrupted during your phone call for a few seconds, that happens all the time. It’s not fine when they’re putting us on hold because another matter requires their attention and they just don’t want to hang up and wait in the queue again later.
I’ll typically wait up to 5 minutes before hanging up. Less than that if we have a lot of calls queued. I have no sympathy for these people, it’s not our responsibility to sit on the phone waiting for them when we have other clients to serve.
