Buyer gets every thing

[nilankarc]

one person purchase a gig from me it was a 3D logo design and he send me a sample file as well. i gave him a developed 2 version. but buyer not satisfy about the work so i design another 3 logo for him with his favor. after delivered he said very poor and ask me to design another. but i said i cant do the work since the order is just basic one . he gave me a very bad review and to remove i had to refund him . he get totally 5 logos as well money. i think fiver should think about this and take action about these type of buyer.
