is POSSIBLY the most annoying thing to hear on a phone call?

along with 'your call is very important to us'.
Really??

i want to pull my ears off.

It's worst when the words are spoken quietly, in amongst really loud hold music - I tend to put the phone away from my ear to avoid the loud muzak, then have a sudden panic when there's a quiet voice in the distance!
