Unhappy customer due to bad service.

My husband bought a kettle at makro strubensvalley, it suddenly stopped working in 6months, took it back, it was taken in for inspection, when it came back after two weeks, it only worked for 2days, how disappointing, they then took it back again for inspection, if something didn't work twice why not exchange it? It costs us petrol to get it back to the store plus we need to heat hot water using a stove using more power, I'm not happy with your service. Start selling quality, so we don't have to keep returning things
