Ok, so my "so called friend" from high school calls me up and requests me for a CMS for his hoax call center business. I didn’t want to do it and didn't have the time so make the busy excuse.
He keeps on insisting and asking it for old time's sake etc.
Finally we decide a price of 80k(rupees not dollars).

I somehow, found the time and made about half of it in 3 days(Laravel rocks) while the time we agreed upon was 1.5 months as I could only work on weekends.

Suddenly he feels, he has got enough to get it working and says just add 1-2 more features, don't make the complete thing. I felt really angry as be was trying to waive off almost all the money as he thought it got done early.

Finally we agreed on 40k, but I wanted some payment up front.
This was 2 months ago. Since then he has ranted about how he has no money but is going to give me as soon as he gets it.

Now, he is dodging my calls and I don't think the the money is ever coming. I desperately needed it for a laptop.

I had already stopped the feature of adding more users(Create) from the CMS.

What do you think I should do?
1 Delete everything (I still have SSH)
2 Send info to all his clients about his hoax business as I have about 200 payment infos.
3 Do nothing
4 {Add your own}
