Lack of Service - Rude Management

I have just had such a disappointing experience with Star Hiring. I was trying to hire items from them to use for an event and while you can order online, there is nothing about dates that you are actually hiring on. I attempted to contact them via email, phone and whatsapp - none of which were answered or responded to. I eventually told them I was going with someone else, and only then did they respond. I told the person dealing with them that I was not happy with the way I was assisted and that I would be taking it further, only to be told "I must do what makes me happy". Clearly they do not need business.
