Not keeping to their moto - passing the buck

We purchased a XBox 1 S from Game Nelspruit 7/12/2017 . The one controller died 20/3/2018 and is still under warranty . Went to game but got told sorry they don't do that anymore it is my problem to contact microsoft and get it sorted out on my cost .

What about their moto and the CPA that the store is responsible for exchanging , refunding or repairing faulty equipment ?

I wouldn't advise anyone to buy a gaming console from them as they passing the buck
