PnP:_"Rusted kettle shows your mettle."

I bought a Mellerware kettle at Pick n Pay. It worked quite well, but the inside became rusted. I took it in and the rusted bottom on the inside was replaced. Not long afterwards the rust started again. Why is Pick n Pay selling such sub standard appliances? Its an insult to all the loyal customers who expect high quality appliances on the shelves in PnP stores. At the moment, I'm using a cheap plastic kettle without any problems. I'm totally disgusted in PnP for the low standards they are maintaining in appliances on their shelves.
