Disgusting customer service

The crazy store in Western Cape,The Brighton square in Kraaifontein. Absolutely pathetic service. I went to buy helium balloons at this store. I was initially serviced by a younger lady,I told her was going to the gym and I would fetch it in an hour, so I paid for 3 helium balloons. She had told me that the foil balloon that she blew the valve was unable to seal so I would have to take another,so after an hour went back to the store,there was a older lady wearing an apron seemed to be a supervisor/manager for 26/4/2024. So the younger tried to grab the foil balloon that she had blown up as it was in the ceiling,and attempted giving to me ,so I said to her didn't you say that the balloon was not fine,older lady jumped in without hearing what was wrong with the balloon and said no it's fine,after the younger lady said what was wrong she said give her another balloon and she proceeded to say well there is nothing wrong with the balloon,just that valve wouldn't close. What was the point buying a balloon just to have the helium escape that made no sense to me? So the young lady asked me choose another balloon and now she put helium in other balloons,but she didn't put adequate amount of helium,so the balloons were small. I asked her is that the size of the balloons she said yes,I have bought balloons from crazy store before and it was never that small,but this was my first time at this store. I was very disappointed and I said that this looks terrible,the older lady was very arrogant and said in an annoying tone,is there something wrong,I told her if I wanted balloons this small I would have blown it myself,she than told the young lady to blow up new ones She told another customer who was at the till who was paying it's too early for this ,making an comment at me by this customer,I did not appreciate her disgusting attitude and will never go there again,she proceeded to look at me while using to burst the small balloons. I wanted to say so much but I just reframed from doing so,this ruined my entire mood and day. I have never expected such terrible customer care from any other crazy store i visited.
