To lodge your complaint about the cancelled Blinkit order and pending refund, contact Blinkit Customer Care directly or use the in-app support chat for quicker resolution. Since emails to info@blinkit.com have not been answered, escalate your issue by raising a ticket via the Blinkit Help section in the app. If the refund is still not processed within 7 business days, you may file a complaint through the National Consumer Helpline (consumerhelpline.gov.in).
