Jumped up yankee!

My Managing Director asked me to arrange a meeting with the Head of Risk Control and a few other people.
Originally, for middle of June and then next week.
I asked his P.A / Secretary or whatever she thinks she is to provide dates.
14th June came back.
The MD then said 'not good enough I want it next week'
So I look at the calendars and I chose just one hour in 3 days where people could do it.
Then the Head of Risk Control replied and said he couldn't make that date and time eventhough his calendar wasn't up to date.
So I was in the middle. I then emailed the MD and suggested he aligned with the Head of Risk as I was just being ' ping ponged'
I receive a call from the MD's P.A. / secretary ranting at me down the phone about contacting him directly, asking him to align, which meant her, she wasn't a secretary. This went on for about 2-3 minutes, which is a long time.
At then of it I just said 'thankyou' and cut the shit off!
As people who know me, someone like this doesn't get away with something like this with me.
I will have to think how to bring her down!!
