Fairphone 4 suddenly shut down and won't restart

Hi Helenreilly,
I received the return from after-sales service after sending my phone, they told me that the screen was broken even though the screen stopped working suddenly without any shock. …
In addition, he asks me to replace the electronic card at more than 200€ in addition to the screen… I don’t understand why if only the screen is broken…
I requested a second opinion

here is some news:
The subcontractor refuses to repair my phone because the screen protection is damaged!
My screen is intact under the protection…
The subcontractor doesn’t want to know anything… I’m at a dead end!
I am waiting for a response from Fairphone to my problem

In addition, they sent me a quote with photos of a broken screen which is not my phone! I find this shameful
