What wallet service are you using? If web wallet then there's a low chance that you can access your private key. In every wallet there is a public key and private key, you only own a wallet address if you have the access on the private key of a particular wallet address/es. And the public key is the one you have to share with others in order to receive bitcoin.
Try to read what is inside https://en.bitcoin.it/wiki/Private_key.

You can't take back your Bitcoin you cant refund it but you can ask the wallet address owner to take back it by sending him/her a small amount with a message.

A private key allows you to spend the value within a public address. If someone else gets access to your private key, they can spend the coins in your funds. It can be compared to your password to your bitcoin address in laymen terms.

You can import private keys into most wallets such as Electrum and then you will have access to all funds on that address.
