No reference number on acknowledgement

[phospholipid]

Hi, I received my acknowledgement of my naturalisation application and it states:

Our ref: SOMETHING
Your ref: N/A

I was told I'd get a reference number, any ideas why I don't have one?

edit: the "our ref" begins with the first letter of my last name and a combination of numbers

You have been given a reference. Just use the Our Ref.
