My spouse visa document return back to Home office

[smcool]

Hi ,

I apply spouse visa for wife in Feb and they returned my original document to end of February. Within 4 days of document revived from Home Office. But unfortunately document not received my address, because i was on holiday during that time, Royal mail sent back my original document to Home office. How do I get my document back from Home office, Which address do i need to send special delivery envelope again to return my document back. Does it effect my application.
I could not find any address from home office website.

Kindly please help how do i get my document back.

Thanks
