Deposit refund and poor service

I must say that I am highly disappointed with Ithemba property management company. I have never had any good or proper service from this organization since I was a tenant until I moved out and now I am struggling to get my deposit refund from them. I moved out on 29th March 2024 and the building manager said my deposit will be refunded by the 15th April 2024 and I will only be charged R140. I followed up today with Ithemba and they requested for a bank confirmation letter to my surprise as I gave them my bank details on their forms when I signed the lease termination forms. They saying I will get the refund within 30 days and I asked if I never followed up today, meaning they would never have processed the refund at all. I had issues when I asked them to make a late payment arrangement for me for 1 month due to financial issues and they have me the runaround and lots of issues after I paid them on time for over 3 years without any complaints as a tenant. This company is very *********** and I would never recommend them to anyone looking for a place to stay.
