Game don't follow their own warranty rules on fixing appliances which are under warranty I am not happy at all

I am so disappointed with game, I bought my Samsung microwave last year August 2021,this year in July stopped working I went to store on the 26 of July 2022 with receipt they took my microwave in for fixing no one contacted me ,on the 18th of August i decided to make follow up I was told there is a quote on my microwave which is under warranty

Your warranty policy says it's under manufacturer policy to fix within 21 days if it took over 21 days you refund or exchange in my case I called after 21 days and i was told that I must pay

You don't follow your own warranty rules where you fail to fix appliances within 21days,and only wen a customer make follow up after a given time and be told to pay you didn't follow your own warranty rules

I am not happy at all with your service
