Have you checked your return tracking number to see if this has been received? All returns are processed within 2 days of being received at our online returns warehouse (this can take longer at peak sale times).
Once the refund has been processed, it can take several days to credit your account. It is also advisable to check the original transaction date on your statement for any reimbursements, as this may pull through on the day of your purchase dependent upon your bank.
If you have concerns over your return being processed, please contact the Customer Service team directly.
