Minecraft - Factions bank

Okay, so me and my younger brother started up a minecraft server. We have essentials and factions. (we have essentials economy) - We enabled economy using the config, and set it so that it took £600 to claim a piece of land.
Next, my brother, who had around £900, tried to deposit money into the faction. No errors popped up. Yet, the faction has no money, and we have to do /f balance to see how much the faction has - still 0.00. No money. Yet, we can claim land - for FREE.2 problems.
So, how do we get it to have the money showing when we do /f f? And how do we deposit money? Help, please.

Added (1). also, why can they claim money free when its set for £600 to buy?

There's an option in the config file that needs to be changed in order for the prices to go into effect.

1. Stop the server.
2. Open your server files (FTP or Local)
3. Go to the Factions config file.
4. Edit config using NotepadC++
5. Go through each line in the config to make sure it is set the way you want it.
6. Restart server.
