huge fee cashing out on ps

hi all,

i was just wondering if anyone else had a problem like this, i won some money on ps, about $400, and it says that $75 will be charged to my card when i do this.

i emailed them and they said it wasnt a fee, that this was my original deposit and had to be cashed out first, now im confused because its not worded like that in the cash out screen.

this is an exert from the email:

"
We can verify that the $73.89 USD you can see from the "Cash Out" screen is not a fee. It is the same amount of your deposit that has to be cashed out first due to our Cashout Policy."

so will i get the full amount if i cash out??
