A client, wanted to buy a Video Site off me.

We decided $80,

He paid $40 upfront.

He wanted me to Make more banners, add more videos, change the skin, and edit it a lot, aswell as give him the site.

So i do all of the above, accept give him the site.

The next day, he says he dont want it.

Do i give him the money back or keep it?

I offered $20 (50%) back and he said no.

Am i in the wrong or what?

I've done that work for f.a basically if i refund him.
