Not quite correct. They usually give the reference number once they have received your application. They say "we can confirm we have received your application and it has been allocated the reference number...."
In my case:
Application sent: 27th Dec
Money taken: 3rd Jan
Confirmation that application received and the ref no given: 6th Jan
Still under consideration but my case is very unique and a number of queries may be raised in relation to my past immigration history so I do not expect a decision soon.
