can i withdraw my funds

Normally once funds are in Apple Account balance the only way to get them out again is to spend them.

From: Check your Apple ID balance - https://support.apple.com/HT202359 -->

"About unused Apple ID balance

You can't redeem or return Apple Gift Cards, App Store & iTunes Gift Cards, or unused Apple ID balance for cash, except as required by law. If your jurisdiction allows for refund of redeemed gift balances, you can contact Apple Support."

A Community Specialist in this topic --> https://discussions.apple.com/thread/253337931 recommends contacting Apple about your options:

If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
