So Jan 15, a buyer approaches me to make 5 game levels and asked me to give regular updates. So I worked on it while giving him regular updates on each level and asked him if he liked it to which he said yes.
Now today , day of delivery , I delivered it to him and now he is suddenly saying "my team changed the idea, we dont want it , we want something else".
Oh and to be precise, he wants new 11 different levels for the same price . So not only he doesn't want to pay me for the work he made me do for so long, he now wants me to work even more levels than before. I have refused by saying politely to accept the delivery for which you made me work .
Honestly , I am feeling so sad , And the fact that he is in full power, all he has to do is just cancel the order and that's it.
What do I do now?
