If you want to get refund from Cash app, but you don’t have any ideas on how long it will take. So, i am letting to know you that, it totally depends on person to person. If there is any individual payment, then you can get back within a second, but if you pay money to any merchant, then you have to wait for 10-12 working days. https://www.email-contactsupport.com/cash-app-customer-service-number/
