Grundig 65 Ggu 7900B TV: Chronically Defective?

I bought a Grundig 65" ggu 7900 b model television 15 days ago. After one week, horizontal lines appeared on the product, and I also expressed my dissatisfaction on this site, stating that I would write about the company's policy. That complaint was satisfactorily resolved. This is stated in the previous complaint. 1- Why am I writing this complaint now? This time, I'm experiencing a TV synchronization error with the remote on a new TV of the same brand. When the control does not press, it detects it and applies all of the commands I gave earlier on its own. I'm having trouble connecting the remote to the television. It's not good. (Because they couldn't match the first installation in the service, they skipped that part) One hour after the TV was installed, I went to the service and purchased the old TV remote, with which I had no problems. It gave me the same problem. Either the TV has a software issue or the Bluetooth integration is broken. I'll have no objections if it's a software issue. However, if it is a hardware issue, I will request that the TV be replaced or refunded. 2- Some TV channels are also not receiving new televisions. I get the error No signal on this new TV while watching the channel on another TV in the same installation. The interesting thing is that I was able to watch the channel on the same Grundig TV that had been changed just a day before. 3- I am unable to use Google Assistant effectively from the remote. It does not fully comprehend my voice command and produces inconsistent results. (I didn't have this issue with the TV that was replaced a day ago. 4- The new replacement TV had a panel of protective transparent tape. However, the old television did not have such a tape. Do you know what I expect from Grundig as a customer who has dealt with all of these issues? —— Dear customer, we sent you two TVs, both of which were defective. We even sent a display item. They claim that we are replacing your product with a higher model at no additional cost as compensation and an explanation for your high customer satisfaction and the problems you have encountered. I will post the information here. The service and the Grundig company must adhere to the policy. I'll also share this on my YouTube.com technology channel, which has 780 thousand subscribers. I hope to conclude this complaint with a thank you.
