Tap Contact Support, pick the category that fits, and describe the problem. You can attach screenshots or a PDF receipt (PNG, JPG or PDF, up to 10 MB each).
We usually reply within 24 hours. The reply lands in the ticket itself, and you'll get a notification — open the ticket to read it and reply back. The whole conversation stays in one place.
The more specific you are, the faster we can help. Include your order number if the issue is about a package.
