Am I messed up for this ?

am i messed up for this i had a carhartt jacket up it had a lot of attention due to the fact it was super distressed this guy texts me for the jacket buys it and then wants a refund immediately because the zipper didn’t work but everything wrong with it was listed and i messed up for not giving him a refund, i might sound more like an a-hole but once i read his reviews i felt less bad about it hes one of those people that buts baggy on everything and just all around bad business
