If the merchant makes your refund, then it can take up to 10 days for the Cash app to receive a refund. As quickly as, it receives your refund, then it will automatically appear on your Cash app balance. If within 10 days you have any queries, then reach the merchant directly to resolve it. If you get any issue there, then use the Cash app phone number. https://www.findcustomerservice.org/cash-app-customer-service/
