LG Electronics review: My lg range

I called customer Service to complain on after cleaning my range knobs that is starting to pit and the coding is coming off and so is the print on the knob so I don’t know what I’m cooking on. I was told by customer Service that it is a cosmetic defect not a manufacture defect and therefore it’s not covered under warranty. These knobs are only 13 months old. I’ve spent a total of $20,000 on lg

products because I was told that they are a good company and they stand by their products and yet I was told by customer service that I cleaned them wrong that you’re not to use warm water with a gentle soap on them. How are you supposed to clean something only using just water I have never heard of that before in my entire life. My phone number is [protected]. My name is Donna Kupferschmid, Donna Kupferschmid my email address is wing [protected]@iCloud.com. I would appreciate if somebody would get back in touch with me because I am very upset and I do not like how Customer Service handled my situation.
