I didn't had the time until now but I have also send an email to paypal (through the messages menu on their webpage as I didn't found any mail address).
Waiting for a response from them.

Any updates on this?

Edit : well, I received an automatic e-mail where it was written to respond to the mail if my issue wasn't resolved, which I did, and that in 24 hours someone will contact me. It was more than 24 hours ago, and no mail or phone call....
