Called extra beforehand if it is possible for me to certify an existing defect on my iPhone for insurance.
On the phone I was told it was not a problem.
When I went there, I was told that it is not possible to certify a defect.
Very bad service, the technician hid behind his colleague and did not even come out of the garage to explain the problem to me.
