Hi Tomislav I understand your concern, however you should refer to T-Com Service if you don't agree with the inspection provided.
You can also bring the iPhone to the nearest Apple Store or Apple Retail Store in order to ask to make a new inspection.
About Water and Dust Resistance on iPhone 7 and later I think you should read this:

The only way to understand if the device has liquid damage or not is in any case to make a physical inspection of the device. You say it was MOINSTURE (maybe) but the repair service says "LIQUID DAMAGE".
The only help you can find here is an answer to your questions, for sure I am not able to warranty a replacement in warranty nor buy you a new iPhone. Please understand I am only answering to your question, for sure I cannot replace your iPhone. At this point I suggest you to speak directly with whom has inspected physically the device or bring the device to an Official Apple Store.
About your statement: "If you don't help I will start to use Samsung or Huawei"... don't know what to say except to read what is displayed at the bottom of this page:
