How to refund entire amount buyer has paid - not just the money I've made?

[golden.throat]

Not used eBay for years, and a lot has changed since then...

I sent an item that has been badly damaged in the post. Looking to refund the entire £5.15 that the buyer has paid for the item, including the buyer protection fee and the pre-paid postage. 

The profit I've made is £1.43. When I click the refund order option, £1.43 is the maximum amount I can refund. Gutting for me but not fair that they're left out of pocket, so want to refund the entire amount they've spent. 

Many thanks for any help.

Buyer needs to open item not as described case.

You cluck refund and it is automatic. 

Ebay will refund BPF.
