Hi! I think you need to find exchange that will suits you. For me now it's Binance which has fees but allows you to withdraw money on your card but now it's available just for BTC, LTC ETH and XPR (here details https://www.chepicap.com/en/news/7063/you-can-now-pay-for-crypto-with-a-credit-or-debit-card-on-binance.html ) . Also I think you can ask somebody who will help you like @firepower I think he can give youbetter advice how to withdraw you STEEM.
