Ridiculous customer service

Today I was at Foschini in Carlton Centre to an exchange. I wanted to exchange for a size then they told me that them item is sold out then I asked for a refund. Apparently, there was no one to assist me the lady who was counting told me that the person who can do an exchange is on lunch. I asked "how come, so now I have to wait for someone who is on lunch. I have to do things according to their own pace?". I asked the lady where the person who can do a refund for me and she said she is at the back and I asked her to call to come a process a refund just a few minutes. The lady said no she can't because she is on lunch it's her time.I got in the shop around 2 and she said if I want a refund I will have to come back at 3. So I spent my money on transport to come and sit and wait for a cashier.I asked the lady that was helping me that how do they let such a thing happen so that someone goes on lunch then everything is on standstill there is no one to assist customers. I am highly disappointed to get such service from such a big company like Foschini, a place where I buy my stuff regularly. The management is highly *********** and they do not value customers at all. I wandered around the shop hoping that someone will step in and help. I ended up going back home without any help..transport money wasted
