Life in the UK error and address error

Hi,

I have two problems, firstly my national checking service sent my application to:

UK Border Agency
Nationality Group
PO Box 306
Liverpool
L2 0QN

However, on your website it states that the application should be sent to:

Department 1
UK Border Agency
The Capital
New Hall Place
Liverpool
L3 9PP

Will this at all be a problem? Furthermore, I had a small error on my Life in the UK test where my forename and surname were switched around. I emailed UKBA and was told to send a cover letter explaining this error, I done this today and sent it to:

Department 1
UK Border Agency
The Capital
New Hall Place
Liverpool
L3 9PP

Which is different to where my application was sent. Seeing as I don't have a reference number yet, I included my full name, nationality, phone number & address. Will the UKBA be able to find my application or will I have to resend the cover letter once I have the reference number?

UKBA have internal mail system where they will direct mails to correct destination.
On your second question the explanation you have provided should suffice.
