Ask HN: Anyone Work at PayPal?

Background: My dad's business is using the (legacy) Adaptive Payments API. When a payment is made PayPal usually sends two IPN messages, one 'Web accept' and one 'Adaptive Payments' IPN.

Recently this second IPN is not being sent for any payments, causing payments to not be processed and customers to be rightfully annoyed.

He's tried to contact tech support but as usual is receiving scripted replies that fail to understand the issue or its severity and just say the account is fine.

Is there anyone that can get this escalated to the right person?

Thank you!

Edit: The account in question is a Singapore-based account, but there is also a UK-based account that receives fewer payments, so he's not sure if that account has the same problem or not.
