Roborock Tricked Me Repair Fee, Warranty Denied, I’m Furious

Our Roborock branded robot had problems with shooting power and charging before the end of 2 years. We called Roborock customer service and they said it could be reviewed under warranty. Since we often hear that the brand is fond of money, we insisted on whether any fee would be defined. Customer service also said that of course, no fee will be charged to you without your knowledge. He certainly did not say that the service charged a maintenance fee, even if the product was not processed. Moreover, the product is already under warranty. We shipped the product the next day. Then they gave us back. They stated that the error in the product was a user error, the product drew water. Robot users know that what they say is not a mistake that can be made. We have already used the place removal feature for a very short time. In that timber, the chamber is filled with water and puts it in place. While the robot is pulling water in, we do not believe that the error is like this, but where is the user error here? They issued an invoice of ₺9.000. They didn't do it when they should have it done under warranty, we didn't insist, so we should have it in this regard. Isn't that the logic of the guarantee anyway? I am a Dyson user at the same time. I call it brand quality, all kinds of support and assistance are provided. Later, we said we didn't want any action and wanted to get a refund. However, the lady in customer service stated that a fee of ₺1150 was charged to us. When I asked what was paid, he said that the technical service was a check fee. Anyway, the technical service has not repaired any malfunction in the product, what is the price? Pay for your technical service as a hassle. At least to the products under warranty. Can such a thing happen? Then, when you first call, if the error in the product appears as a user error, state that we will pay the fee, even if you will pay us just checking the service, so do not trap people. I will definitely not leave this behind. The lady in customer service closed my face. Can there be such disrespect? Are you such a cheap brand?
