Bad customer service from new world

Just had bad experience on the phone. I bought a Hisense LCD 55" TV on the 14th of July for my son only to find out that he had bought one already. I called new world Menlyn to find out what is the procedure when bringing goods back. I recieved a rude suprise wen I spoke to a man by the name of LESLY who was very rude when he told me that I should leave my name and number and he will get back to me, I asked LESLY wether he would get back to me today about it and he was just flat out arrogant and rude with me and he even hung up the phone on my ear I wonder if their calls are recorded? Please help because it is my money that I used to support his business and just because I want to return something "LESLY" gets rude with his customers.
