Online Banking System

I was trying to do an once off payment and the system forced me to choose a public recipient. Then when i receive my proof of payment the account number is wrong. After calling the call center they advised me that this is a reference number linked to the account and not the actual account number. Please change the way this works - it makes no sense. I should be able to manually enter whether i choose a private or public recipient. Please fix proof of payment to show proper account number..
