To receive reply from dept not named person

[HowToDealWithItAll]

I sent an important (non-work) email to a team who use a shared email address for enquiries. My salutation named individuals e.g. Dear Mrs Bloggs and Mr Smith.

The reply is from the shared email address but signed off in the body of the text as "The xxx Department"

AIBU to want to know which human being wrote the reply? What is a polite way of requesting their name? I don't want ill-feeling in further correspondence but I also don't like personal responsibility being shirked.

I suspect they don't want their name associated with my enquiry because someone at their end has failed to do something they should have done.

My team works like that. We work 24 hours, when USA close down, India takes over. When India closes for the day, Europe takes over, and so on.

As the manager, I can see who answers what. Just because You can't see a name, it doesn't mean their manager can't either

YANBU OP. It's impersonal and gives the impression of trying to shirk accountability. It also means that you end up explaining things a lot because all this alleged reviewing of the case notes doesn't really happen. I think it's unprofessional and poor customer relations.
