Order and payment help
Keep your order ID and the email or phone number used at checkout ready. For payment questions, RetraLabs can review the payment status returned by Cashfree without asking you to share card, UPI, or banking credentials.
Certificate of Analysis support
If you need a lot document or notice a mismatch between a label and a COA, contact support before using the material. Include the order ID, product name, and batch reference where available.
Delivery and damaged packages
Photograph the outer package and product before opening a visibly damaged shipment. Contact the support desk promptly with the order ID and images so the team can coordinate the next step.
