A friend was trying to send me bitcoin using the btc atm, she sent the funds without putting my QR code but her phone number instead of my qr code to which my wallet address is linked with.. Please this friend of mine doesn't even have a wallet address but the bitcoin was sent and it seems like a wallet address was generated for her and we don't know how to retrieve this bitcoin back, can you help?
