Registered letter by certified mail

Dear members,
recently we received a registered letter by certified mail, unfortunately the post office refused to give to Geert because my name was written above  FMBB instead of FMBB and my name under the club name. So the post office said that I was the only person that could pick up the letter.
I live quite far away from Koekelare the town it was send to.
So I think the club will receive it back. We have no idea from who it came, so this message explains to the sender why it came back, Please send it again to the correct address.

This is the correct address for all correspondence:

Mr. Geert Bouckaert
FMBB Secretary
Swytswal 13
8680 Koekelare
