Root Cause

• Missing or invalid contact information: The customer did not provide valid or complete contact details required for identity verification.
• Incorrect data format: The provided contact information (e.g., email address or phone number) does not meet format validation requirements.
• Mandatory contact fields left blank: Required fields such as email, phone number, or address were not filled out.
• Verification dependencies: Accurate contact details are needed to trigger verification processes like OTP, email confirmation, or phone verification.

Troubleshooting and Solutions

• Ask the customer to verify and update their contact information, ensuring all required fields are completed correctly.
• Ensure that all necessary contact fields are enabled and collected mandatorily from customers in the checkout.
• Ensure that the email address and phone number provided are valid and formatted correctly.
• Retry the transaction only after valid contact details have been provided.
• Inform the customer that accurate contact information is critical for processing payments and identity verification.
• Implement form validation to prevent submission of incomplete or incorrectly formatted contact details.
