how to get money from a reluctant client?
Firstly, I know this is not a programming related question at all, but I have done everything that I can, read every blog about this that google could show me, and tried half of it all but my client is just hard as a rock to get past.

I completed this website 4 months ago. (I would like to keep the website anonymous - if this post comes up on google search for his customers, it will have a negative impact on his business). We did several iterations, he was very demanding (and nosy), I complied with every single thing he wanted, including the font-size of the footer which destroyed the aesthetic looks by quite a bit. (and he messed with the colors too, making it look dangerously childish and unprofessional) 

Anyway, he was very friendly during he whole process. After getting all the requirements I accepted to build the website for £950 and I charged him £150 in advance so he wouldn't want to bail out after I started the work. The requirements kept changing quite a lot, I made adjustments as and completed the website just 5 days late, w.r.t. the agreed date, in-spite all the changes in requirements.

that was four months ago. he has never returned my calls nor replied to my emails since then. How do I get the money back from him? I really need some advice on this,  this is the second time someone has not payed me.
    
**points to be noted:**  
1) we did not sign any contract.    
2) I still hold the passwords for ftp, cpanel and everything. I dont want to bring the site down. somehow it doesnt seem ethical to me.  
  
  
ps: sorry all you admins, i know this is not a programmatic problem but I dont know where else to seek help. If you want to delete this, of course, please do.
