Industry: Retail & Convenience Stores (Monoprix, Franprix, Vival, Spar)
Jurisdiction: France
Primary Regulator: FCD (Mediation) and DGCCRF (Consumer Fraud)
Important Safety Warning: Beware of fake customer service numbers on search engines. Scammers frequently target consumers with fake “account suspended” phishing emails or fraudulent loyalty card (Casino Max) points scams. Groupe Casino staff will never demand you buy gift cards to resolve an issue, nor will they ask for your account password over the phone.
Level 1: Customer Support (Service Client)
- For Large Supermarkets/Hypermarkets: Stop! Groupe Casino sold almost all of its large supermarkets to Intermarché, Auchan, and Carrefour in 2024. Even if the sign still says “Casino”, check your receipt. Your legal dispute is likely with the new parent company.
- For Franchised Proximity Stores (Vival, Spar, Petit Casino): If you had an issue at a franchised corner store, you must complain directly to the independent franchisee who owns it. Casino corporate is not your direct contractual partner for that specific sale.
- For Direct “Casino.fr” or Corporate Stores: Use the online help portal, or call the central customer service line at 0 800 13 30 16 (toll-free from France).
- Availability: Customer service phone lines generally operate Monday to Friday from 9:00 AM to 12:00 PM and 1:00 PM to 5:00 PM (CET).
- Timeline: Standard inquiries are resolved via chat or phone within a few business days.

Level 2: Formal Written Complaint & Mise en Demeure
- Who to contact: Formally escalate a direct legal dispute (such as an unhonored statutory warranty or a missing refund for a corporate-owned store/website) by sending a registered letter with acknowledgment of receipt (Lettre Recommandée avec Accusé de Réception - LRAR) to their legally registered global headquarters.
- Address: Address your letter to the Legal/Customer Service Department, Casino, Guichard-Perrachon S.A., 1 Cours Antoine Guichard, CS 50306, 42008 Saint-Etienne Cedex 1, France.
- Timeline: A legally binding deadline of 8 to 14 days (set via your Mise en Demeure) provides the company a strict timeframe to resolve a standard financial dispute before they legally default and you escalate to mediation.

Level 3: Regulatory Authority / ADR (Médiation)
- Consumer Mediation (Mandatory): Under French law, you must attempt mediation before going to court for claims under €5,000. Groupe Casino is a member of the Fédération du Commerce et de la Distribution. You must file your dispute with the Médiateur de la FCD. (Note: Franchised stores may use different local mediators listed at their reception desk).
- Government Fraud Reporting: Do not use SignalConso to ask for a personal refund. Only use the DGCCRF SignalConso platform if you suspect widespread illegal practices or systemic consumer law violations.
- Timeline: You can open an FCD mediation case only after you have sent a written complaint via LRAR and received a negative response (or no response after 60 days).

Level 4: Legal Action
-
Pre-Litigation: You must have proof of your written complaint (LRAR) and proof that you attempted mediation (FCD or the local franchisee’s mediator) before a French judge will hear a small claims case.
-
Court/Arbitration (The Privity Trap): If you attempt to sue Casino Guichard directly for a defective product sold by an independent Spar franchisee or a hypermarket recently sold to Intermarché, the French court will dismiss the case due to a lack of privity of contract. You must sue the specific legal entity on your receipt.
-
Filing the Lawsuit: For direct disputes with Casino Guichard under €10,000, private consumers can bring their case before the local Judicial Court (Tribunal Judiciaire or Chambre de proximité). Claims under €5,000 can be initiated via a simple declaration (Requête) without needing a lawyer.
