Oros Apparel

I bought a jacket online from OROS, order #*** on February 25, 2020, delivered February 28, 2020. I did not like the material and the jacket was too large so I returned it the next day and asked for a full refund.
On March 7th I was notified that the return was processed and that they would process my refund.
Subsequently, I received a voucher (not my refund) for $127. I have emailed 3 times asking for a full refund but not received a reply.
On March 13, I was notified that I still had my voucher!
I called the OROS number *** at the Revdex.com site (***). It does not appear to be a working number.
I also called another OROS number found online, ***. This did appear to be a working number but, even though I called at 1:27 CST, I had to leave a message because no agents were available.
What should have been a seamless return process has been very time-consuming. I try to buy less on Amazon to support smaller businesses, but if OROS cannot simply refund my money I cannot recommend purchasing ANY products from them.

In early-February 2020, I purchased a jacket from Oros for $134.99. The Order number was ***. The day it was received, I emailed the company that it did not fit and requested authorization to return it. An email was sent to me authorizing the return. On February 25, 2020 at 8:05 pm, I received an email from Oros "Exciting News Jonathan. Your return was delivered to Oros. Once the return has been processed, you will receive an update." Over the past two weeks, I have sent multiple emails requesting the status of the refund. I have also left multiple voicemails with the phone number on its site. None of the emails or voicemails have been acknowledged or returned. I want a full refund for the jacket to my original payment method.

December 28, 2019 - I bought a jacket from Oros Apparel via their website for the price of $320 USD.
January 2, 2020 - The jacket was delivered to me. The jacket did not fit so I went on the Oros website and followed their instructions for returning the jacket.
January 6, 2020 - I printed the FedEx return label provided by Oroas and I mailed the jacket back to Oros.
January 10, 2020 - I received an email from Oros confirming they received the jacket I returned.
January 20, 2020 - I sent Oros an email requesting information regarding my refund. No response.
January 21, 2020 - I sent Oros a second email inquiring about my refund and I received an automated email saying "Our customer service team operates Monday-Friday from 9-4pm EST and will respond to your request as soon as possible."
January 23, 2020 - I sent Oros a third email inquiring about my refund. No response.

I purchased a coat on January 7th, and returned it to the company because the fit was off. They sent confirmation that they received the package on January 17th and would issue a refund when it was processed. Between that date and now I have sent 4 emails to the company to inquire when I would receive my refund because it was taking so long, and have not received a response yet. They do not have a contact phone number on their website, only an email address. They owe me $280.00 for the product. Please help.
Thanks
