Horrible service at makro woodmead

My partner and I bought a tv on the 13th from Makro woodmead and because the woodmead store was out of stock, they gave us a demo. However the remote provided to us was incorrect, we were advised to keep coming back as they were busy looking for the remote. We came back countries times to check with the sales guy, we even checked via WhatsApp where we were ignored. Today we finally decided to bring the tv back as the attempts to get the remote have been in vein. We were advised that the 14days has lapsed & that we won’t be refunded, they called the manager who was awfully rude Vincent Lemoane w, he even walked away from my partner as he was talking to him. We are currently at the store and no one is willing to assist.
