unfair billing

i resides at Jabulani Lifestyle estate block c317; i have occupied the unit since the 1st July 2019. when i moved in NO INSPECTION was done till to date. I informed the maintenance manager that was in charge then about certain things that i found broken etc... one of it was the kitchen cupboards shelf; and he told me that he will send people to sort it out. i think this year Jan; maintenance guys came and fixed it. now i am being BILLED for it? Why? sent an e-mail to customer care as per protocol and the response back is "THE POTFOLIO MANAGER STATES THAT YOU ARE LIABLE" for what? can i get this corrected because right measures where not taken when i first occupied the unit.
