Rovalle Estates refusing to pay deposit

They no longer take my calls because they keep giving me excuses about my deposit. I gave in the key on the 26th, was told I would get my deposit by the 7nth and I'm still waiting. My calls go unanswered and I'm close to escalating the matter. theyre the ones that said I must move out month end but now I must be given a run around. if they were waiting for readings then why not have the money in hand and then just deduct when reading come (which they have by the way) and paying immediately? now I must beg for my own money?
