The number 01 78 91 82 56 appears on many contact sheets associated with Cdiscount. In practice, this number leads to a very limited interactive voice response system (IVR) that redirects most callers to the online customer area or the FAQ, with no guarantee of connecting with a human advisor. Understanding this operation helps avoid wasting time on an ineffective channel.
IVR of 0178918256: what really happens online
User feedback collected on forums between 2024 and 2025 converges on one point: calling 01 78 91 82 56 triggers an automated voice menu. This menu offers standard choices (order tracking, product returns, billing), but each option redirects to a web page or a pre-recorded message.

Connecting with an agent remains exceptional via this number. The IVR does not offer a traditional waiting queue or automatic callback. For so-called “classic” orders (appliances, high-tech, furniture), the system loops back on itself and eventually hangs up or repeats the URL of the customer area.
We recommend considering this number as a passive voice information channel, not as a true point of contact with customer service. The distinction matters: calling multiple times will not change the outcome. You need to go through other channels.

An article detailing the customer service hours for Cdiscount at 0178918256 confirms that the IVR does not provide access to a direct contact for the majority of requests.
Numbers for Cdiscount that are actually operational by service
Cdiscount segments its contact channels by activity. Using the wrong number extends the resolution time by several days. Here are the verified channels:
- For an online purchase on the marketplace, the 09 70 80 90 50 remains the official customer service number for Cdiscount. This non-premium number allows access to an advisor after going through a more comprehensive IVR than 01 78 91 82 56.
- For Cdiscount Travel, the dedicated number is 09 77 40 91 17. Advisors exclusively handle flight, stay, and package bookings.
- For the former Cdiscount Energy service, the historical number has been deactivated since the portfolio was sold to Elmy in 2023. The only valid number now is 09 80 80 20 31, reachable Monday to Friday from 9 AM to 6 PM.
Trying to reach the energy service via an old Cdiscount number results in either a dead tone or an error message. The migration to Elmy has led to the permanent closure of Cdiscount Energy lines.
Cdiscount Mobile: a 100% digital model without a phone number
The mobile branch of Cdiscount has eliminated all customer service phone numbers. Support is exclusively through online chat, accessible from the Cdiscount Mobile customer area. This architectural choice is not trivial: it reduces operational costs but requires the customer to adapt.
The chat hours are set. Outside of these slots, the contact form takes over, with a variable response time. No number, including 01 78 91 82 56, allows you to reach a Cdiscount Mobile advisor.
For urgent requests (lost SIM card, blocked portability), we observe that chat remains the fastest channel. Going through the form extends the resolution by at least one business day.
Contact strategy for a quick response from Cdiscount
The classic trap is to multiply calls to different numbers in the hope of reaching an advisor. This approach is counterproductive: each call generates a distinct ticket, which fragments the file on Cdiscount’s side.
Prioritize the online customer area
The messaging integrated into the Cdiscount customer area centralizes exchanges. Each message is linked to the order number, which speeds up processing. Advisors responding through this channel have access to the complete history of the file, unlike agents from the phone IVR.
Escalate via social media
When the internal messaging does not yield results within a few days, posting on Cdiscount’s social media often triggers a faster response. Community managers have direct access to resolution teams and prioritize public requests to limit the impact on brand image.
Recourse to consumer service
If customer service has not resolved the issue, Cdiscount Mobile has a separate consumer service, reachable by mail. This formal route is the only one that opens a traceable complaint right in case of a persistent dispute.
Time slots and actual availability of Cdiscount advisors
The hours displayed on official pages do not always reflect actual availability. The 09 70 80 90 50 operates on weekdays, but waiting times vary greatly depending on the time slot.
- The early morning (before 10 AM) and late afternoon (after 4:30 PM) concentrate call peaks. Waiting times can exceed half an hour.
- The slot between 10 AM and 12 PM generally offers the best pick-up rate.
- On Saturdays, when the service is open, availability drops significantly compared to weekdays.
For Elmy (formerly Cdiscount Energy), the Monday to Friday slot from 9 AM to 6 PM is strict. No phone support is provided on weekends or public holidays.
The 01 78 91 82 56 does not communicate specific time slots since the IVR operates continuously, but the absence of a human advisor behind makes this availability theoretical. It is better to focus contact attempts on channels that actually lead to a qualified interlocutor, targeting mid-morning slots.
