Buyer's should be able to 'ban' terrible sellers

This user 'asadiqbal1988' was meant to rewtite my content and instead changed literally 5 words and I paid him $10. He has now given me grief not agreeing to cancel and laughing saying he wont ever provide me refund.

Fiverr customer support also after 3 messages saying they wont provide the refund. This is disgusting I can't believe this crap customer service after I've bought over 190 gigs.
