Siemens KG76PACI0N Late Service Appointment Complaint

I bought a Siemens KG76PACI0N refrigerator today and immediately needed support from the authorized service. However, the authorized service only offered me an appointment on 16.07 between 14:00 and 16:00, which is a very long time window for a newly purchased refrigerator that needs to be put into use. During this period, my food will have to stay outside and this long, vague appointment interval is extremely disturbing and impractical. For such a basic and urgent need, I find Siemens’ service network and appointment planning clearly insufficient, and I do not find it acceptable that a faster and more precise solution cannot be offered. I request that an urgent service be provided in a much shorter and clearer time window and that the problem caused by this inadequate service network be resolved as soon as possible.
