Wrong Document Delivery for Tier-2 Visa Extension

Hello,

I had applied for my Visa Extension-Tier 2 with an application Number 1212-xxxxxxxxxxx. I was supposed to send all the documents to address (Tier 2, Tier 5 Standard, PO Box 74576,LONDON, SW1P 9WP) but at the Biometric time, I got confused and send all the required document (Passport, BRP etc) to wrong address (3rd Floor, Lunar House, 40 Wellesley Road, Croydon, CR9 2BY) by mistake.
The letter was received by them on the morning of 23rd July-2018 at 7:41 a.m. It was posted under my name (Vxxxxxx Sxxxxxx).
I am really confused now as what to do beauase it contains all my important documents and unable to track how the process work.
