UPDATE: 12th JuneI have sent an email/tickets everyday this week and still no response from Oura.I returned the ring within the 30 day return window on the 16th May. Oura confirmed I would be refunded in full. The ring was delivered back on the 19th May and receipt confirmed by Oura.I have now sent 6 emails requesting an update on where the refund is. Joseph and Maggie in Oura support initially provided different answers on the refund status and now will not return emails or support tickets.I just want my money returned to me. Desperately poor experience and I would caution anyone to deal with Oura after my experience.
