Bosch Air Conditioner Not Reconnecting To Wi-Fi After Power Cuts

I have been using a Bosch air conditioner in my home for about three months, and since the first day I bought it, there has been a persistent Wi‑Fi problem. Whenever there is a power cut, the air conditioner does not automatically reconnect to Wi‑Fi, and I have to manually reconnect it every time. This situation has become very annoying in daily use. I contacted Bosch customer service about this issue, and a service team was sent. The service team stated that they would consult the factory and get back to me, but no concrete action has been taken so far. Every time I call, I am told things like “we will ask the factory”, “we will ask Germany”, “we will call you”, but the last time the service came was about two months ago, and since then no one has called or informed me. About a month ago, I called again and asked whether there was any response from the factory, and I was told that there was still no response and that they would get back to me, but I still have not received any information, and I continue to reconnect the device to Wi‑Fi manually after every power cut. I am dissatisfied both with the technical problem of the air conditioner and with the lack of clear and timely feedback from the service and the factory. I request that my air conditioner be promptly resolved in a way that it automatically reconnects to Wi‑Fi after power cuts, and if this is not technically possible, that the device be replaced with a properly functioning one or that a refund be provided.
