The service is appalling and very disgusting

The service is appalling and very disgusting. I went to Clothing Junction in Philliphi Cape town (The junction mall) , Friday morning to purchase some items for my sister and later that same day went back to return some of the items as they were small and didn't fit her, we were told you can't return things bought the same day and was told to come back the following day for a refund. Went there again today only to be told they don't have cash available. Now I need to go there for the 3rd time for the same thing and not knowing what to expect. It's beyond frustrating yesis I left the store very angry.
