Disapointed by Smeg

I bought a kettle in less than years the knob for switching on and just came off,went to their offices in Umhlanga,they said ok they will send it to Johannesburg so I waited 3weeks on the third week they called me your kettle is back please come and fetch it

Went there to collect I asked ok so what did they do the lady told me they gave you a new one I said ok but when I looked at the kettle it didn't look new so I took it home As soon as we fill it with water it was licking ok again I took it to them they said sorry maam we dont know what they did in Johannesburg, so I showed them that this is my old kettle they just removed the cover so there was a gap that is why its licking This is the 3rd week again I'm waiting for them to call me nothing ,so I'm very disappointed because Smeg appliances are not cheap so I expected better customer service
