You'll need to provide some additional detail

1. How much in Euro's did you give to your bank?
2. How much in Euro's did your bank charge for operating the transfer?
3. What exchange rate did your bank apply?
4. How much in Peso was eventually transfered directly into the Philippine bank?

Whenever I make a transfer I know exactly all the above.
The final amount of Peso is ALWAYS exactly as predicted and stated to me, without fail.

Just for discussion purposes, P1000 is quite a small amount, lets say around Euro 18

So you give your bank Euro 18 and they charge say Euro 10 in their charges/fees that leaves Euro 8
The exchange rate from Euro to Peso is say P48 so the Peso transfer is 8x48 = P384

I'm not saying that's correct or that's what you paid, just outling the process.
