Daikin Turkey Did Not Deliver The Air Conditioner Outdoor Unit

I purchased an 18,000 BTU air conditioner direct from Kaira Turkey via the Hepsiburada website. 15 days later, it was delivered. When the Hepsijet cargo arrived, it stated that there was only one indoor unit. They searched their warehouses for the outdoor unit but couldn't find it, so I contacted Kaira Turkey, who said they would create a record from the call center and get back to you. I've called 6-7 times since Friday and still received the same response. They can only say that we have transferred it to the appropriate unit and will return when there is an update. During this process, I sent a message to the company via Hepsiburada and was told that they would first check with the cargo company for two days, and if the device could not be found, it would be sent again. On the sixth day, which is today, it is stated that the product is out of stock and waiting for more. There was no date or other information specified. I contact the call center, and they say they don't have any information. I ask them to transfer it to the appropriate unit, but they say it cannot be done. It's incomprehensible that an air conditioning company has no stock. Then send a higher model, and I say I don't want to wait; I haven't received a response other than that we have transferred it to the appropriate unit, and they will contact you. Definitely do not purchase this device. Daikin is behind it, but they handle the process worse than any other shopkeeper in the area. It has already been 21 days since I purchased the device. The device will be added to the stock, shipped, and delivered by Hepsiburada. The service will then schedule an assembly time based on the intensity, and they will come and install it. At best, it will take about two months. Whether they will install the device I purchased at the start of the summer in July or August is a complete mystery. According to articles 8 and 11 of the law on defective goods, I want to use my right to replace it with a defect-free alternative that cannot be provided.
