Beko 12000 BTU Air Conditioner Installation Hassles and Lack of Service

In September 2022, I purchased a Beko 31225 model 12000 BTU air conditioner. The service team that came to install it in the Sanliurfa Haliliye Paşabagi neighborhood claimed that the internal infrastructure was ready. When we asked for the materials, they said they couldn't provide them because there was pre-existing infrastructure, but they did make a note on the service record that if we moved within the warranty period, the next service team would check the record and not charge us based on the note. We moved to Istanbul and requested service from Beko, but we didn't get an appointment for another 6 days. The Beko headquarters mentioned an installation fee of 1350 TL, but the service team later demanded 1500 TL. Regardless, I agreed to it. The new service team, on the other hand, informed us that they would not refer to the previous record and insisted that we provide the materials if we didn't have them. I contacted Beko headquarters and asked for the initial installation service receipt, which has yet to arrive. I filed a complaint, but they delegated the evaluation to the service team. "Dear customer, your service request with reference number 446959605 has been canceled by our Authorized Service due to a lack of spare parts," the service team responded. If you have any further questions, please contact Arçelik Customer Service at 0850 210 0 888." When I contacted customer service again, I was told to contact the installation team to resolve the problem. What am I supposed to do if I don't know who they are? Your representative accessed a record on their behalf. Do you know what materials your own installation team employs? How did a well-known company like Beko end up in this situation? We used to rely on you for everything, but perhaps we should reconsider. According to the service team, the material costs 750 TL per meter, and we need at least 8 meters, for a total of 6000 TL. Is it my responsibility to pay for this? You should have supplied the materials from the start; it is your responsibility. If your service team is behaving maliciously, you should keep an eye on them. Beko must communicate with their service team to resolve this issue. I'm looking forward to hearing from you soon.
