Your complaint has been resolved. Notification of the result has already been sent to you.

Curenergía Comercializador de Último Recurso, S.A.U. is committed to replying to any claim in as short a time as possible, taking no longer than one month from the date of receipt at our claims centre. The reply's purpose is to inform the customer of the actions that have been or will be taken to resolve the incident raised in the claim. A reply does not necessarily mean that the incident has been resolved. This is because actions may often be required that take longer than the established time limit for replying.

We are also part of the arbitration system. You can see all the information here.
