These days there are e-mails with deceptive content relating to a fake "Invoice compensation detail" sent only apparently from the "enel.com" domain.
Here's what the communication looks like:
Enel Energia invites anyone who receives a e-mail or suspicious text message not to open or click on the links in the texts, not to download and open attachments (Enel does not send excel), to pay lose attention to any requests for personal codes or confidential data (for example user or passwords, access codes) since Enel Energia never asks for such codes.
If in doubt, check the authenticity of the request through the usual contact channels: toll-free number 800.900.860 and website www.enel.it/en.
