The Vamos Refund Policy is the document that governs this. The summary below is here so you know whether it is worth reading.
A subscription can be refunded if you ask within fourteen days of your first purchase and the account has used no more than 200 credits in that period.
Promotional and discounted subscriptions may not qualify. If something was broken rather than simply unwanted, that is handled case by case and may end in a full or partial refund.
How to ask
Email contact@getvamos.ai, or open Live chat from the user menu. Either reaches the same people.
Tell us which workspace it is and what happened. If a payment went wrong, the invoice number saves a round trip. Open the invoice from Settings, then Invoices to find it.
After it is approved
Allow three to fifteen business days for the money to appear on your statement. That window is your bank's, not ours, and there is nothing on our side that speeds it up once the refund is sent.
Cancelling instead
If you have passed the fourteen days, cancelling stops the next charge and you keep full access until the end of the period you have already paid for. If a payment is failing when you cancel, access ends at once. See Managing your subscription.
