How do you contact Home Office about BRP inquiries?

[PhillytoManchester]

How does one contact Home Office with inquiries about their BRP? The email address in the pamphlet we received comes back with an automated message stating they only answer emails that are in response to their own. All others will be deleted.

We've called the phone the number from the Home Office site which is no longer in use:
BRP card management service
0300 123 2412

Nationality & Citizenship number said I should contact Visas & Immigration. That phone number said there's no longer a way to speak to BRP on the phone.

There are only two options on Home Office site:
- report it lost / stolen
- apply for a new one

Thank you!

I would also like to know if there's any way to contact them?
My BRP never arrived and the DX courier are saying it was delivered to me but they can't tell me who apparently signed for it, only the sender, aka Home Office, can.
It's such a headache and waste of money for me to have to cancel and apply for a new one over something their poorly chosen courier did.
