Is endesa.com Safe?

Endesa is one of the main energy providers in Spain, offering various electricity and gas plans. Here comes their first advantage: you can have both, from one supplier and that would make your life easier… no need to deal with multiple companies. Its customer service is generally helpful in case you need to contact them or need additional information, and the billing system works fine. I have never experienced any trouble with them, which is not always the case with other energy providers.
