ATOMIC RANGE ONLINE STORE NOT EXISTING

I ordered an extra battery for the ecoflow river inverter from atomic range online store in February 2023 and have not received my battery. I emailed the company canceling the order and requesting a refund. However there has been no response to the emails that I sent. The website is no longer a secure website, so I can't access it. The phone number when called ends immediately with message call ended. It seems as though the company is no longer existing.
