Bosch Heat Pump Faulty Since Installation - No Repair Despite Weeks Of Delay

I purchased a Bosch heat pump in August 2025 and had it installed in Malkara, Tekirdağ. From the moment it was installed, the device turned out to be faulty. On 7 November 2025, a request was created for the defective part, but despite the passing time and the weather getting colder, the problem has still not been resolved. Although I have called customer service and the authorized service many times, I am constantly told that the process is “in transfer” and I feel that I am just being stalled. Bosch is not standing behind its product and, in my opinion, has sold me a defective product. For this heat pump, I paid ₺180,000 and my invoice information can be checked via the phone number 0 (531) 6** 25 7*. For communication, I request that you contact me via 0 (553) 9** 19 9*. I request that the faulty part of my Bosch heat pump installed in Tekirdağ, Malkara be replaced by the authorized service as soon as possible and that the problem be finally resolved without any further loss of time.
