Is there any contact number for a Cash app refund?

Before making any transaction on the Cash app, you have to ensure the recipient details like mobile number, email address, or bank account details or debit card number, #Cashtag to avoid issues. If you make any wrong payment and now want a refund, but, if that person denied for Cash app refund, then you can’t do anything. So, you have to ensure all the things that I mention including internet connection.
