Thank you for getting back to us, @HGA. I understand encountering some challenges with the app with finding the partial refund options can be a hassle, and I want to ensure that I help you by providing an alternate way for a partial refund in the MSC.

In your attached screenshot, you have the Activity & Reports tab, and we can issue the partial refund through an alternate way. You can follow these steps:

1. In your MSC account, pick Transactions from the Activity & reports dropdown.
2. Enter the appropriate date range, then Search.
3. Select the Transaction ID or the transaction you want to reverse.
4. Choose Reverse (Void/Credit).
5. Type in the amount you need to refund, then Submit.
6. A receipt of the transaction will be displayed on the screen. Select E-mail or Print to get a copy of the receipt.
   

Next, I encourage contacting our Live Support team for an update on the ticket submitted regarding the missing Processing Tools option in MSC. They can access your account in a secure environment, assist you in conducting further research, and create an investigation ticket if needed. Here’s how you can contact them:

1. Click on the Support tab.
2. Enter your concern about the missing Processing Tools in MSC.
3. Select Continue.
4. Choose Chat with us, or Have us call you.
   

When this is resolved, I'm adding this guide about understanding fees for refunds or voided transactions: Understand fees for refunds or voided transactions.

I appreciate you for your patience and understanding, HGA. I hope the instructions about the alternative way of issuing a partial refund in the MSC help you in the meantime.
