Visa fee receipt

Hello everyone,

I have recently switched into Tier 2 General category from the old style work permit. I had sent it my application via post and paid using my credit card. I have received the decision letter, my passport and BRP card.

Now my query is that is it possible to ask UKBA for a receipt of the visa fee? I require a receipt to get it reimbursed by my employer. However, none of the documentation sent by UKBA mentions that a fee of XX amount has been received and my employer wont' accept the credit card statement only. Can someone please suggest something? Thanks.
