Tango Blocks All My Payment Attempts, Shows Payment Incomplete for No Reason

Hello Tango Support Team,

I don’t know why I’m having trouble recharging through your app and the Tango website. I’ve tried using different cards, but it still shows “payment incomplete.” I already checked with my bank, and there are no blocked transactions from Tango. This issue started today, and I’m not sure what caused it. I haven’t violated any of Tango’s terms. Please help me resolve this. Thank you.
