The whistle is leaving the kettle

Having purchased a Berlinger Haus Kettle, via a third party October 2019 and then being replaced due to damage, prior to use. This kettle is in constant use on a gas stove. Not only is the paint around the belly discoloring to a gold colour. The kettle cannot be cleaned when it is hot, as the paint tends to rub-off. The pain is very susceptible to minor dings. This is very poor quality for a supposed premium brand item.
