Balloon attraction - Total waste of time & money

Somewhat unprofessional, I paid her in full before the event to ensure smooth sailing. On the day, loadshedding kicked in unexpected as we hadn't had the entire week & it lasted 4 hours. The lady was unprepared for this (she had no manual pump as backup). She did make a plan, which I was grateful for but my expectations were slowly diminished because she was rushing to another appointment & whilst setting up the balloon hoop, she was having a full on argument with the next client because she hadnt received pmt as yet (so not focusing on the job at hand). So whilst all of this is happening she says that it looks like she hadn't blown up enough balloons for the hoop (this was supposed to be the main attraction). Needless to say she rushed off to her next appointment. The balloon arch looked really shoddy so my guests and I ended up blowing balloons that I had brought along for something else & completed the arch. Was a total waste of money. She hadnt even called back to apologise. I believe in supporting small businesses, but at some point there has to be accountability. Utterly disappointed.
