Refused to Exchange DOA Goods

I purchased approx. R9000 worth of Everlast and Trojan Gym Equipment on 10/01/2016, After spending 5 hours assembling the equipment , I found a hole in the seat and a broken ***** on the Everlast Hardcore bench that I purchased. I returned to the store with the damaged seat and ***** and asked them to swap it out. The sales person known as shimmy refused to exchange it and referred me to customer care , I went to the customer care and they called the supervisor who refused to provide me with a new seat insisting that it goes in for repairs. This is brand new Work out bench that I just paid for , so I insisted on a new one . Shimmy starts shouting at me and point his fingers at me . We went to another supervisor Shaun , he insisted that shimmy give me a new seat , which was resolved rather quickly after waiting for an hour and having Shimmy shout and scream at me. I wont buy from Game or any of the mass stores subsidiaries again, I spend over R100k per annum at these stores, Makro ,Game, Builders and I have one small problem and its too much effort to fix it.Mass Stores are cheap but I am not sure its worth the headache, I will rather spend more and get better service elsewhere
