How to get my fund to my credit card or my bank account

Ethereum is NOT fiat currency, like what you withdraw from your bank. So, you need to send Ethereum to an exchange. Sell/trade it for your native currency. Then setup your bank with the exchange. Withdraw your funds to your bank. This is not related to MATIC/Polygon Network. If you need other assistance, search YouTube or Google for tutorials. Thank you.
