Karcher KHB 6 Pressure Washer Battery and Charger Not In Stock

I bought the product khb 6 pressure washer with battery from the company's own website, https://www.kaercher.com/tr/ev-bahce/mobil-temizlik/khb-6-bataryali-basincli-yikama-makinesi-13280100. html , this is the address of the site, but the company sells the product but does not sell the battery. When I corresponded on the web page before purchasing the product, I was told that it would come until the beginning of August, so I bought this product, but now they say that they do not have the battery, but it will be available after six weeks, I don't understand why you are selling a product that does not have a battery, we buy this machine not for decoration but to use it, BUT IT MAKES NO SENSE TO BUY ANYTHING WITH BATTERIES FROM THIS COMPANY, I HAVE EXAMINED THE PAGE, NEITHER THE CHARGING UNIT NOR THE BATTERY OF ANY BATTERY PRODUCT IS ON SALE AND THEY CANNOT FIND ANY SOLUTION FOR INTEREST SEARCH AND PROBLEMS. IRRESPONSIBLE COMPANY.
