costume order for a party

they promised to make my son's costume exactly as i sent them to be,turns out to a disaster and if i complain they telling me it's look almost the same which is not true.and they dont deliver in time.now am asking for a refund and they refused,telling me to send it back so they can fix it.how possibly is that because they took almost a month to do it and now i have 5days to my son's birthday party.am really disappointed and ****ed off ,cause i should have other options if they didn't promised to deliver,now i wasted my time and of course my R750 for nothing.now i have to look around for other outfit.
