I’ve just tried to ring the claims department of NRMA insurance, where for 15 minutes of being on hold I’m repeatedly told

“… we realize that your time is valuable. Please continue to hold and a member of our team will attend to your call as soon as possible”

If they truly did think my time is valuable, why are they asking me to continue to hold for an indeterminate amount of time, instead of either
a) giving me an indication of waiting time, or
b) giving the option for me to leave a callback number?

I gave up after 15 minutes – after all, my time is valuable, NRMA Insurance told me so.
