very poor customer service

I bought a salton kattle and toaster on the 23rd of July 2017. Since last week I notice that my kattle is problematic evertime I switch it on then it will go off again so on Saturday I decided to take it back to Mr Price home in Randfontein where I bought it. Well I got there I spoke to the branch manager (who wasnt very helpful at all). She said that she wants the the box of the kattle which I dont have however I still got the boxes where the kattle and toaster where packed individualy and i still got my receipt. she basically turn me away saying that she doesnt have any instock and that I should go to keywest. Now my question is, is it not her responsibillty to make sure that I get a new kettle or a refund why should I as the client go where ever and try to get help somewhere else. I`m with Mr price home for a very long time and I have to say that im utterly disgusted and dissapointed with the treament i got from Mr price home . and the saddest part is im still sitting with the faulty kettle. If this is the way Mr price home treat their clients then I dont want to be one of their clients anymore. I`m closing my account and Iwill take my business elswhere where I will be treated like a valued customer. the worst part is that im still in my 1 year warranty period?? just the mere fact that she didnt even tried to help me makes me very angry.
