Unable to Return RGX Sheriff Purchased in Valorant – Riot Games Support Unresponsive

I purchased the RGX Sheriff in Valorant today and would like to return it. It's been less than 14 days since the purchase, but I’m facing issues with the Riot Games support process. The Riot support website is giving errors, and I can’t access my account to submit a request. I’ve also reached out to the support team, but I haven’t received any response.

I need assistance to process this return. Can anyone guide me on how to proceed with the refund? I would really appreciate your help. Thank you!
