3b, An order for the payment of any other money which is due.
If you want and I really hope you will do this cause it seems you kept your side of the contract and its an act of being dishonest not returning a deposit,
You can go to contact the Lands Tribunal and see what they say. I recommend sending a registered letter.

If you can go this way then you can make witness reports to say everything was okay and challenge the landlord.
