We've all done it: You get put on hold while you're chatting with the bank or your energy supplier, and you find yourself singing along to the hold music while you wait to be put through to an employee who can help you.
If the call isn't going well, you might even have muttered something under your breath because you think no one can hear you.
If you've ever found yourself in either of these situations, then we've got some unfortunate news for you - as it turns out that call operators can still hear you once you've been put on hold.
