Does anyone believe it's a good idea to wait this out?

My situation is that I have some USD sitting on my CEX.io ledger, and withdrawal attempts to a verified payment card are being rejected for no apparent reason. My last successful withdrawal was on June 1. There are no responses from support. I could possibly buy bitcoin on their trading platform and withdraw to another wallet (I see one reply here that btc withdrawals are working fine). Does that seem like a good idea? Or does anyone have any recent information from a support rep that would help me feel better about waiting this out?
