Sent PayPal an email they replied with generic answer but unable to reply back

[SpaceAlien]

I have a problem with my account and wanted to tell them how bad customer service I got so I sent email to them.

they sent back a generic response and said if this does not solve your problem reply back and a support person will help.

so I replied back and hit send.

error - problem occurred cannot send message.

i tried 10 times.  I tried without VPN and tried with VPN.  I had no problem sending ANOTHER email but I cannot reply back to original!
