Before you write about a payment

It helps enormously if you include the email address on your account and roughly when the charge was made. If you have the Razorpay payment ID from your receipt, send that too — it lets us find the transaction immediately.

Our Cancellation & Refund Policy covers the usual cases and may answer your question faster than we can.

A note on what we can and cannot help with

We are an education business. We can help with anything about your account, your purchases, or the material itself. We cannot give personalised investment advice, recommend specific trades or instruments, or manage money on your behalf — see our Terms of Use.
