Before taking any action, you must first contact your supplier to report your problem.
You will probably do this first by telephone. You should then confirm your conversation in writing (ideally sent by registered letter) so that you give your supplier formal notice to find a solution to your problem.
Next, if your supplier does not respond within ten days, you can contact the DGEM to try to find a solution.
Disputes concerning your electricity bills
If you are disputing your electricity bill, you must first do so in writing (ideally sent by registered letter) to your electricity supplier before contacting any other party.
You should only contact the DGEM if your supplier fails to respond to your request. The DGEM then contacts the supplier on your behalf.
If you are disputing the content of a bill, the role of the DGEM will be limited to ensuring that you receive an adequate response from your supplier.
