The only way to do it is through the form. Did you use this one?
Once you receive an automated reply, you need to respond to it directly (even if it's from a no-reply) and it will be sent to the staff.

Yes I did use that form, I chose "I want to close my account permanently" this then takes you to a help page which directs you back to the "form" and you go round and round in circles.
I chose the option "I still need help" and got an automated email which directed me to the same "form" and to this community. I replied to the no-reply email address as people on the forum suggested and have heard nothing back.
