Simply disgusted by Game manager

Im so disappointed! I've called Game Galleria a few days after lockdown to report my TV stopped working, I've been considerate due to lockdown much couldn't be done. I've since called the store twice every week since speaking to a supervisor named Neville who said continuously he had my details & he was polite. Today being 23 May I've spoken to Nevilles manager who's name is Sam whom I've spoke to on 3 occasions. I told Sam that I'm getting frustrated because he gives no solid answers & I heard of game stores in other provinces helping customers & he is OK because he had a TV in his house so he doesn't care about customers & go's around in circles with no solid answers. To my shock Sam said to me "I DON'T KNOW WHAT HAPPENED TO YOUR TV IN YOUR HOUSE... YOU ARE COMPLAINING ABOUT YOUR CHEAP TV IN YOUR HOUSE, I'VE GOT A 13K TV IN MY HOUSE" and he cut the call on me. I've called Neville directly thereafter & I told him what Sam had said & he agreed his manager should not have spoken to me that way.. I've asked him to ask Sam to call me back & nobody has done so. I'm very disgusted with the service. I've been without a TV for almost 2 months now.
