Unhappy customer

On the 20.03.20 I bought a TV at hi fi n1 city.......the TV screen then started to turn green (LCD). I then called hi fi corp contact centre and they advised ne to take the TV to the nearest hi fi corp store...I then went to hi fi corp n1 city today.... While standing in the q the security at the door told me that I cant bring the TV back because the assessing department it close it will only open on level 2....I then asked to speak to the store manager,the store manager came outside addressing me outside and she told me that they can't replace the TV because the repairs department will only open in level 2..I then asked her to contact the regional manager so then told me she can't...when I asked her to provided me with the regional manager contact details she told me if I'm unhappy with my service I should contact the call centre....

I mean this TV isn't evens two months old yet and this is the service I'm getting from hi fi corporation...I purchased my TV cash and this is the thank you I'm getting......so now I paid R4000 for a TV that's broken when I asked her to refund me she also said she cant.... So do you guys just make money out of us customers.... This is really really bad
