CDB Residency (Thabo Sehume) refusing to give me my deposit

CBD Residency (Thabo Sehume Building) 247 Visage st, Pretoria central is a ****!!

1. Upon renewal of my lease, They increased the rental price from R2400 pp to R4500 pp for sharing. 2. Then decided to take my child out at the end of our contract.

They have been refusing to give me back my deposit. Every week they promise to pay me back my Deposit. Now their phones are off.
