Jaguar — Poor quality of tapt

I bought a Jaguar kitchen tap on 12.11.2016. The quality of tap was poor. After two years small spots seen on the spout. Two months before a small hole was developed on the tip of spout. One month before the spout broke down.The spout inside found rusted. The service agent told me that at the starting stage we would replace it . Now at this stage we cannot do that
