Reaped off

i bought an apartment through Chartwell in 2023, the agreed repayments of R897K including levies and water and electricity R10500 and now i'm paying R13 500 extra R2500 and getting charged for water and electricity on my statement by chartwell and Alphameter. How can you pay same thing twice? When you ask about it they it is shared property payments for for garden, electricity outside your unit. And yet the material used in the unit it of cheap cost because it breaks from time to time i had to fix my own bath tab when it was blocked.No one cares they want money at the end of each the month.
