The first step is to contact the OPC or the CEME, through the channels provided by the companies.

If the OPC or the CEME don’t respond, or if you are not satisfied with the response you receive, you can submit your complaint or enquiry to ERSE via the Electronic Complaints Book.

ERSE responds to all enquiries and follows up on all complaints submitted through this channel, which are automatically sent to us.

The paper Complaints Book remains compulsory in all establishments that provide customer support services.
ERSE receives a copy of all complaints submitted through the Complaints Book (physical or electronic) and of the replies that, within 15 working days, should be sent by the OPC and by the CEME to the consumer. There is no need to duplicate your requests.

If you don’t agree with the OPC or CEME reply or if you don’t receive it within the deadline, you can request ERSE’s intervention, by filling out the form.
