Please Retrieve Diamonds That I Mistakenly Send On My Tango Account

I mistakenly sent 399 gifts on my Tango account and cannot retrieve them. These tokens were sent in error, and I’ve repeatedly requested their return from the recipient, but they are refusing to send them back. The tokens belong to me, and I urgently need assistance in recovering them. Despite my attempts, I cannot reverse the transaction through the app. Please help me resolve this issue and ensure the tokens are returned to my account as soon as possible. I appreciate your prompt support.
