To ensure a quick and smooth refund, it's important that you contact us as soon as possible if you've made a duplicate payment. We always try to reach out to you when we spot a duplicate payment, but if we're unable to get in touch, your refund may be delayed.

If you've paid an invoice twice, you'll need to raise a support ticket via the customer portal with the following details:

  • Invoice number
  • Payment date(s)
  • The bank account number, Bankgiro, or Plusgiro number you'd like the refund paid to.

Once we have all the details and have located your payments, we'll process the refund.
