I don't need to call them ... but I'm going to call them now.
I think it's outrageous that people that don't need to talk to them should have to wait so long in order not to say anything. Any delay when you have nothing to say is deeply frustrating. I normally have to make a note of what I'm not going to say in case I forget. But now - as a result of these delays - I've decided not to make a note. They'll then have to be patient whilst I try and remember what I wasn't going to say. That will teach them.^
