bad treatment

I had payment problem, called and arranged with nokwnda as she is my agent and agreed that on the 18th I will make a payment and I also want to serve a notice. on the 18th I paid and short with the money for another room, I communicated with her and we agreed that they will use the money for the deposit since I am moving out. yesterday when I came back from work my kids were locked outside, and no communication was made with me. I had to call her I go few kilometers to a place to get the keys, today when I come back they are locked outside again, still no communication was made with me. it really sucks as she is not being professional with me, especially when I made arrangement with her and they have my deposit. she inspected the rooms and no damage was done, meaning I am entitled for my deposit. I hade the fact that she didn't give me the contract for the room.
