Cash app offers you two ways to make a transaction here. If you make a transaction through a standard deposit, then it can take up to three days to show the amount into the Cash app account, but it is free of cost. But, if you opt instant deposit for bank transfer, then you have to pay a 1.5% charge fee. Here, you can make Cash App Dispute for any unauthorized transaction. https://www.yahoocustomer-service.com/blog/dispute-a-cash-app-payment
