Oura Ring Oura Accepted Payment for Smart Ring, Sent Wrong Size. Took my return. Has not exchanged or refunded money. No communication from company. Many people experience similar issues.

I saw a Facebook advertisement for Oura Ring (smart device). I ordered the ring from their website in November 2021. They sent a 'sizing kit'. I selected my ring size and submitted it to their website. The ring they sent was the wrong size. There is no phone number to contact this company. I initiated an exchange online and returned it to the specified FedEx dropoff center. The item has been received by the company, yet I do not have a replacement or any prospect of one. I have received no communication from the company about the exchange. 

Please note that I have followed up several times by submitting a ticket or email. I received one reply, which I responded to, and have not gotten a response. (over a month ago). After I complained on their Facebook site, I received a direct message from Oura, asking what my registered email is, but have not gotten a reply. 

The company's Facebook page seems to have hundreds of complaints, similar to mine. 

The summary is that they took nearly $300 from me, and I do not have a product to date.
