Enormous costs for transaction

[APres]

Hello,
My friend should send me some money (390 €). 
Before to do it with Paypal I checked and I saw that it should cost him 3.99 Euro and nothing to me.  It was OK.  
So he transferred it.  And I received not 390 € as meant but 368,63 €.    
No idea why what is wrong.  And how we can resolve or revert it.

Sounds as if he sent the funds using the goods/services option instead of using friends/family and so you were charged a fee.

He says that he choose it right.
But 

a) Even for goods/services it is enormous commission (more than 5% ?) 
b) can it be corrected or reverted?

Hi @APres,

Thank you for your post!

Typically, when a refund is sent back to the original sender, the initial fee would not be refunded. You can see more about fees here. If you have any other questions, you can reach customer support by clicking 'Contact' at the bottom of any PayPal page. Support is also available if you send a DM to @AskPayPal on Twitter or a PM to facebook.com/PayPal.

I hope this helps!
