unable to withdraw

using USDT to withdraw, send to account team , system ask me to upload QR code and wallet address , then first time they tell me need to verify, OK, i wait until I got the mail told me all verified. I go wesite withdraw again, still same problem, i can not click submit button, system pop up a notification to ask me upload a QR code, but once I upload QR code, the system then POP up notification, ask me old one already exists, please upload a new one. So this is strange, which i use this "old one" to verify, and they said is ok, I also got a new mail tell me that I do not need to upload QR code! And then the department ask me to try again, and screenshot the problem, which I sent them from the very original one. IS there anyone same problem with me ?
