Hello S.,

• Don't mix class, deployment and activity diagram?
• What is your goal?

Here is a proposal using deployment diagram, as:

@startuml
skinparam rectangle {
  BackgroundColor #E0E0E0
  BorderColor black
}

rectangle Customer 
rectangle Bank 
rectangle "Payment System" as Payment_System 

Customer --> Payment_System : Payment Details
Payment_System --> Bank : Payment Request
Bank --> Payment_System : Payment Confirmation
Payment_System --> Customer : Payment Receipt

Enjoy,
