Mafadi Property Management's unfairness and croockery

I needed an office space for business presentations, I got in contact with an agent called Lunga Nkosi who gave me a lease and said to pay 2 months deposit. The place adn't had power for many years, no service delivery(pile of gabbage is heaped on the corner of the premise), birds **** eevrywhere on the verandas and stair cases and toilets out of order but still open for use.

I spent only 3 weeks having moved in after the 7th of June and contacted Lunga around the 16th to tell him I was moving out. The agreement was that I would only pay rent once the power was restored, all the while I had been promised that power would be restored on the 1st of June before I moved in to the offi space I rented but it never happened. When I contacted Lunga and told him I had already vacated the premise and handed over the keys to william the caretaker, he said I need to email him and formally submit my notice for 1 month, which I did and when the month was over he said he would follow up with accounts because there is a penalty for terminating the lease early. To which I rep**** and mentioned all the reasons why I could not use that space due to hazardous and way below standards condition of the premise and I have videos to prove it. Lunga began ignoring me so I contacted Salim, the maintance guy whom I had met once at the premise and he gave me the lady's number who is in charge of accounts, her name is Lilian Bondokoto. I phoned her and explain my case then sent her all the email communication between myself and Lunga then she said she wanted to call Lunga and get clarity first then she would call me back.

I phoned her again multiple times before she answered then she said she had responded to my emails, when I checked she wrote back saying I am simply not getting back my deposit because I terminated the contract before 3 years.
