Bad customer service

We bought a tv about 7 months ago. One evening the screen went blue. Took the tv back. The gentlemen working at that stage in the back was very helpfull. So i went in today 28/02/2022. To go and fetch my new tv as the old wasnt replaceable. So as i walked in the gentlemen in the front was very helpfull until i went to the back where a lady or guy is working. I think its a she. What a very rude person. The way she spoke to me was shocking. How on earth do you employ such people. I dont think i will ever buy again from you. Because your customer service is not up to standard.
