Exchange policy

I exchanged shoes for a dress at Rage Jabulani mall and was not given a slip( around 24/11/2017) only to find that the dress is small and needs to be exchanged as well.I then went to Rage Maponya to exchange and was advised they cant exchange the dress as my purchase is over 30days, the dress isn't damaged and has tags on. The staff advised they cant call Head Office or anyone as they know my exchange wont happen this is even after i made it clear that i dont want a refund and wont mind to top for something else. I was then given an option to SMS Rage customer care, i received a call back 02/01/2018 Palesa on the line asked" where was I this whole time" as i failed to meet the exchange policy- her attitude was appalling and she was dismissive of what i had to say as a client, with both the store and contact centre staff I was never given an option or possible solution, instead it was confirmed that Rage has my money while I have an item I cant use.
