Pre-launch grievance contact
Takumi KokawaRepresentative Director; proposed interim escalation contact
Kabushiki Kaisha Fermion, trading as InshiHub
8F MIEUX Shibuya Building, 5-3 Maruyamacho, Shibuya-ku, Tokyo 150-0044, Japan
Email: contact@fermion.company
Telephone: not yet available
A formal India-facing Grievance Officer designation is not asserted. The named representative is shown only as the proposed interim escalation contact while the required corporate designation, telephone channel, and India-specific arrangements are completed.
Fermion has not yet published a customer-care telephone number. Checkout will remain disabled until the applicable Dodo transaction seller and every required India-facing customer-care channel are confirmed and displayed.Fermion's India-resident nodal-contact and local service-agent positions, the exact Dodo transaction-seller entity, and the allocation of India-facing grievance duties remain under written review. These unresolved arrangements are disclosed in the seller information and prevent checkout from opening.
Submit online
The form issues a non-sequential complaint reference immediately. Keep that reference and quote it to track the complaint in any follow-up.
Email alternative
- Email contact@fermion.company with the subject "India grievance".
- State the affected page or product, the issue, the requested outcome, and any important date.
- For a future order, include the order or processor reference and purchase email. Attach only the minimum screenshot or file needed to explain the problem.
Do not send a full card number, card security code, password, one-time authentication code, or online-banking credential. We will issue a complaint reference in the acknowledgement; quote it in every follow-up.
Response standard
- We will acknowledge the grievance within 48 hours.
- We will investigate fairly, request only relevant information, and aim to resolve the grievance within one month of receipt.
- If a final answer cannot be provided within that period because information is outstanding, we will explain the reason, action taken, and next expected step. This does not extend a shorter deadline required by law.
- A complainant may request internal review by replying with the complaint reference and the reason the proposed resolution is insufficient.
Proposed Dodo payment and transaction support
If Dodo approves and processes a future order, the applicable Dodo entity will be the transaction seller and will review payment, duplicate-charge, invoice, refund-status, fraud, or dispute issues under its Buyer Terms. Product-quality, content, corrections, fulfilment assistance, and accessibility issues remain the responsibility of Kabushiki Kaisha Fermion as product supplier and product-support provider.
A purchaser will be able to consult Dodo's charge and refund guidance page, which points to the transaction-specific support email, use the route shown in the checkout or receipt, or use the customer portal for a transaction issue and may contact Fermion at the same time for a product issue. The guidance page is not represented as a formal grievance-intake form.
External consumer channels
Contacting us first does not waive a consumer's right to seek help elsewhere. Indian consumers may use the Government of India's National Consumer Helpline for pre-litigation support, including helpline 1915, or use the Government of India's e-Jagriti portal for available consumer-commission services.
Nothing on this page limits a non-waivable right to approach a competent consumer authority, commission, court, data-protection authority, or other forum.
Current purchase status
Purchases are unavailable. Dodo Payments merchant and product review, the exact transaction-seller entity, India-facing responsibility allocation, and the live payment-delivery-refund journey are not yet approved. Current grievances can relate to the public website, samples, release-alert records, privacy, or accessibility, but no valid InshiHub India purchase can presently be created.
