Tango Tipalti Withdrawal Declined and Money Not Refunded

I use the Tango application and on 31 August I requested a withdrawal of 554 dollars via Tipalti. Later I saw in the transaction history that this payment request was declined, but the 554 dollars have still not been returned to my Tango balance or paid to me in any way. I contacted Tango support about this rejected payment and shared the relevant screenshots in the in-app chat. Despite this, my problem has not been solved and I have not received a clear explanation about where my money is or when it will be refunded. I request that my 554 dollars from the rejected withdrawal on 31 August be urgently refunded to me and that I be informed in writing about the reason for the rejection and the refund process.
