Heavenly Intercession

Your Grace,
My intercessor saint doesn’t seem to to anything for me, I see the my friend’s intecessors do things for them but nothing for me. Is there someone I can speak to register a complaint or file paperwork changing my saint.

Sayedna,
When we die and if we go to heaven, can we choose which heaven we go to? I mean if I go to heaven, I’d like to go to the Islamic heaven, they’ve got rivers of wine that doesn’t cause hangovers, endless feasts and naked servants of the opposite sex. That sound like a good time and I wouldn’t mind spending eternity there. Also, I mean if we’re already going to heaven, what difference does it matter, which one?
