I'm getting so pissed off by this client, here's the gist

We signed agreement defining the following deliverables:
- news page and news article page
- releases page and release info page
(it's a guy from a record label)

After the signature we (me and my colleagues) went to work and finished all that (+ a little more actually, yea I know never overstep your agreement right but we did) and we got paid (all good)

Now after payment he's asking us to do more (some kind of mail installation thing), so I obviously tell him, as I actually have many times before, that our agreement only stretched as far as those 4 deliverables and we wouldn't work without a new agreement defining a new set of requirements or an hourly rate.

Next he goes and tells me the following
==
We already have an agreement. I'm not paying you on an hourly rate as you are not next to me. Let me know
-- First off no we don't, the agreement only covered the 4 pages
== immediatly after
Also you really need to work on your costumer service. Your attitude is very rude. I don't know how many clients you have but all this distrust attitude is not in your favours. Let me know if you want to proceed?
-- Are you fucking kidding me? I am rude and distrustful? I JUST DO MY FUCKING JOB YOU PRICK

Sorry just need to let off some steam
