Poor customer service from Superbalist

So this is not the first time my order has been messed up by Superbalist but it is the first time that I am seriously angry and displeased with their service because I ordered an item that I really wanted and had been waiting for, for a while due to the size not being available and then I received the incorrect item and size. When I went to exchange it, the sizes were all sold out and now I am angry because I can't get the item I really wanted. Last time I wanted something and then superbalist had the incorrect inventory displayed on the site so the item was never actually available and what did Superbalist do? They tried to console me with a R50 voucher. Is that seriously all they could offer too? Then on a another occasion they gave me a hat instead of a shirt. This doesn't even make sense. Incidents like this are what make me think twice about supporting this business because they aren't even attempting to get me the right item. The consultant that answered my query told me to log a refund but I want the item that I paid for. I did not have time to respond to the agent yesterday so they closed my query. I don't see why superbalist gets 48 hours to respond to me but I only get 24 hours. Its like they just wanted to get rid of me and move onto the next query. They didn't even offer me a voucher this time so I guess they get cheaper and cheaper as time goes by.
