Sounds more on the line of, poor business practices. I'd suggest finding another bank.
However, if your hellbent on going through with a working, this should do the trick.
The Green Skull Candle Spell :
1. A Green Skull candle -or- a green votive candle.
2. A pencil with a very sharp point.
3. A "Better Business Money Drawing" Oil -or- Olive Oil.
4. A fire-proof dish or bowl.
5. Matches, lighter, or lighting tool
Hold the candle in your left hand. With your right, pick up the pencil and write your exact desire. You're carving each letter with the pencil tip (these grooves are important).
Place the candle in your chosen dish or bowl, then pick up the oil. Place a little inside your left palm, and rub your hands together. Pick up the candle with your left hand, and gently message the candle in both hands. Vision your desire as you do so.
When you're ready, place the candle back in the dish or bowl, then light it.
It must be in a place where it won't be disturbed, as the candle must burn down and out.
No doubt, or it won't work.
