Confused buyer and seller's frustration

[aniksikder]

Hello everyone , I am new seller in fiverr, few days back i got an order from a buyer. At first he wanted unlimited revisions but i concluded in two and he accepted the custom order saying yes.

I finished the product as asked or discribed and sent a sample so that he get to know the outcome. After that he kept making changes with additional requirments and demanding this and that. Moreover, he is ordering me in such a bad manner like he bought me for his work ! I at least gave 8-10 revisions in quick chat and delivered the product with another after delivery revision. Now he is giving false accusation and asking for more changes . what should I do ? 😦
