There are several ways in which you can register a complaint at DED and these include telephone, fax, email, website or a personal visit to DED Consumer Protection division.
In all instances you will be expected to provide your name and contact details, full details of the retailer/service provider and a description of the case to be lodged. You should ensure that all supporting documents related to the case are with you at the time of lodging your complaint.
The Consumer Protection division will provide you with a unique case number which should be quoted when enquiring about the progress of your case which we will seek to resolve within two working days.
