Very unfriendly contact: For a repair offer (No estimate) of my Galaxy S8, in which the display is torn, to pay CHF 43.00.- I find a joke ... Especially since the phone still works perfectly and therefore must be disassembled by any technician. .. (Supposedly this is the normal process at this company and the phone will also be dismantled a repair offer?)
Other companies create repair offers for free !!!

Addendum based on your answer:
Thanks for your answer. When creating a cost estimate, the associated costs are logical. However, for a repair offer (offer), so I can forward this to the insurance, I just do not understand away. The device works properly and has no interference or restrictions. This was also communicated.
The same day I received the repair offer from another company for free ...
I wish you all the best in the new year.
