Fraudulent scheme impersonating Orange's name

Hello,

I was a victim of a scam today. A number called me this morning, saying there had been an outage in my town and that I needed to immediately call a number starting with "0026". They insisted several times that this number was free, completely costless. Out of naivety, I contacted this number and the same lady answered. She told me that now, to verify the line, I needed to take my mobile phone and call the same number back. I found that strange and hung up. But she called back, insisting that I must not hang up as it would block the update. So I did what she told me, I stayed on the line. After nearly half an hour, I hung up. The lady called me back, I told her that I couldn't call her back and she said that when I had the time I should start over. I went to the Orange shop to find out if I had been a victim of fraud or not, and indeed, I had. After contacting the number 3009, which is indeed free, I was told that I had been scammed and that I was not the first. A very hefty bill came in, and I am really upset... Do you think there would be a possibility for me to be reimbursed at least partially? I am really upset about getting scammed; we don't even know who to trust anymore! I just want to know if it would be possible to get a little compensation, thank you!
