Samsung Q70D TV Delivered with Screen Damage, Horrendous Customer Service

We bought a Samsung QLED Q70D 65-inch TV on Friday, July 19th. The authorized service came to install it on the evening of July 23rd. After the installation, we noticed a film on the corner of the screen that looked like a screen protector. Not knowing what it was, we called the technical service within 15 minutes to get information, but no one answered. The next day, we messaged them and, on Wednesday, July 24th, we created a request and sent photos. The technical team responded rudely, accusing us of damaging the product. We insisted that we did not cause any damage and were told to contact the head office. On July 26th, we did so, and a service ticket was opened. We were informed that they would inspect the product between 1 PM and 4 PM on July 27th, but no one showed up. They closed the request, stating that the inspection would be done for a fee, which we did not accept. There was no call or SMS about the closure of our request, and we waited all day for the service that never came. We called customer service for information and were frustrated by the lack of response. We hope you can resolve this problem promptly, given your reputation as a global electronics company. We chose your brand because you are known for high service quality, but we have been disappointed. We urgently request that this issue be resolved and our television inspected before the replacement period expires.
