Once the retailer has processed your refund the money should reach your original payment method within 5-10 working days if you paid with a debit or credit card.
If your purchase was made via a buy now pay later provider, the money will be refunded to them and they will refund anything you've paid against the purchase. This could take up to 30 days.
If you need more information or assistance, you must contact the seller and allow 48 hours for them to resolve or respond. OnBuy Customer Care team will be unable to assist until you've been in contact with the seller.
