Microwave was good before I return it after returning it came back with scratches and rusty

I bought a microwave on January 2025 On Feb 2025 my microwave light went off . I took the microwave back to homechoice hebron mall where they logged to be repaired it took 1month and 2weeks to get it back

My microwave had no scratches only light went off The day they brought it back it had scratches and rusty on top . I called homechoice hebron mall branch let them know about my microwave the lady didn't give me her name she said "I will enquire will call after few minutes" I waited 3hours untill I called back "am still waiting" the lady said for what I explained about everything she kept on saying this will take long I don't advise you to take it back .that's where I asked her why are you telling me that you don't want me to complain while I spend R2400 on a simple microwave while I could have get samsung so I should let my microwave be in rusty and scratches that's where she ended the call
