Area-51m R1, bad customer service

Hello,

I have opened one case with Dell. After 2 weeks of changing e-mails I was informed that my display and cooler is faulty.
The e-mail told me that the service person will arrive to fix it. After a confirmation from a person that he will be arriving at my location on 16.10.2022 at 11.30 he was delayed without notifying me. During this time I have made another appointment for 18.10.2022 because it's normal for me do infor the second deadline that I've entered into Dell system was not technician that he is unable to come at the agreed time and date.

After this experience I've been told that my case was escalated. After this second deadline was skipped by Dell because it was in their system, normally it was overlooked. Now I have been trying to solve my case, but after talking for about 50-60 and being transferred from one person to another - each time spelling out my name, date of birth, e-mail address, service number, case number I'm only being transferred - until I got disconnected.

I've tried calling the Austrian numbers - that don't work - numbers are disconnected or my connection is not possible - because probably I need to pay to get in touch with Dell. But it's great to pay to confirm my identification and what happened to be transferred to the correct person or department.

After trying to get international support - that is in fact only valid in UK  - because it's a international call only for UK and "I am sorry sir I can not help you as you called UK number and we can only verify your name and service tags I've been rejected."

What can I do to solve my case without having to call for 1 hour and get disconnected? When I tried to send an e-mail I am receiving a response after 1 day or longer and by the time that I replay back (under 1 hour) I enter in another sleeping area that lasts for days?!
