looks like your landlord used up your deposit and waiting for another tenant to come in so that he can pay back your deposit. hahaha....

on a more serious note, your landlord is very unscrupulous.

you need to note down the events i.e. telephone calls, verbal promises or test msg etc...

if you have a tenancy agreement, you need to prompt i.e. write to him of the provision that requires him to return your deposit after the tenancy has been terminated. Give him 14 days to respond to your letter, if no news then you can proceed to:-

(a) lodge police report; and
(b) file a complaint with consumer tribunal.

You should arm yourself with all the facts before you go to the police station and consumer tribunal.

LOL wadafuq?

anyway, do you have a tenancy agreement with the landlord in the first place?

What does your agreement say about return of deposits?
