Welcome to our transparency mailbox, your contribution will be very valuable and taken into account.

At this stage of the process, it is important you are as clear, objective and honest as possible, describing the cause that supports your complaint; decisions that may affect third parties depend on this.  We remind you that your complaint can be anonymous or personalized.

Next, we ask you to select the mechanism for registering your complaint:


Line 01 8000 915 537

In all of the cases, we will treat the information you supply in a confidential way and it will be attended as soon as possible. We ask you to keep full discretion of your complaint in order to achieve a better and effective action by the Ethics Committee.
