Communicating via email to get a desired result

Hello There,
I’d like to get an external perspective and advice on how to approach a business related issue.
I have delivered a series of workshops for a private university. Due to their internal issue (I don’t know what it is) they only paid me 60% of the promised rate per hour. I flagged this with my point of contact 2 months ago and he forwarded my request to their finance department. No response from them. So I then emailed their finance department a couple of times myself and they just don’t reply to me.
In my head I’m pondering how best to construct an email to them so that they actually do pay what they owe me. I don’t want it to come across as I’m begging for my fee or that I’m disappointed with them and don’t trust them any longer.
It would really help me, if you could suggest how I could look at this situation from a different perspective – as I feel I’m disappointed and frustrated with them ignoring me and it’ll show up in my email communication. And this won’t get me to the desired result.
Thank you.

 

Answer:

Hi, love. Wonderful question. Why is it a problem to feel disappointed and frustrated and communicate that?
I’ll never argue that feeling that way is enjoyable, but I will argue that it’s not a problem to have those feelings in the first place.
However, if you think that bringing a different feeling to your emails is important, then here is my question: what feelings do you want to come to your emails with? What thoughts do you need to think to feel those feelings? If you were to bring those desired feelings to your email, what would you sound like? What would you ask?
Of course, the default desired result is that other people do what we want them to do…right? ALAS, we can’t ever control other people. So, make sure that your R answers this question: what is your desired result for YOURSELF?
And when you say “I don’t want it to come across as I’m begging for my fee” just know that is your Thought about you sending this email, so be sure to clean that T up too!
