Payment summary is displayed in "Money Sent & Received" section of the app. Click on the specific payment and you'll be able to view its details. For data privacy reasons you will not be able to see who has paid the payment request. 
In the Payment Summary, you can view the Payment Reference, PaymentID that should match with the payer, date and time when the payment was completed and the bank that was used to complete the payment.
