unhappy with fiverr seller - any recourse?

i purchased a custom gig on fiverr the other day to have a whiteboard video created.


in the person's demo the voice over work sounded fine so i paid extra to have the seller add voiceover to the order and paid for rush delivery.


when i got the demo the audio sounded like the voice was being run through a computer generated program......basically i was very unhappy.


i informed the seller who took 2 days to try again with another voiceover artist who sounded like she was a 12 year old girl.


so i ended up having to get someone else to do the voiceover and pay them....adding to my cost and further delaying completion.


i recently asked the seller to adjust the price since i felt the voiceover work was not acceptable and since these deladys made this anything but a rush order and he absolutely refuses to do so and is acting like he is doing ME a favor by synching up my audio file and no additional charge.


is there any way to cancel the order with him or am i stuck with my only recourse being to leave negative feedback?


just doesn't seem fair that when you order on fiverr if the seller does a far less than satisfactory job they get paid anyway.


won't be using them again for specialized type of work like this. this was a custom gig for over $100 not a 5 dollar throw away.
