Consultant not taking accountability

I started flat hunting on the 22 May 2020 and signed up contract on terms that rent will be R3500 then parking be R350, so i remember very well that i spoke with their consultant Zandile Siwela on the telephone call after i sent her an email confirming there isn't gonna be deposit required on this special of reduced rental, she confirmed yes. But now I'm disputing the rental invoice that's looking a messy and I'm being told of fees i never agreed on, they want me to provide them proof and i don't have some since some clarity i got on a telephone conversation. Firstly i am very disappointed at the level of incompetence shown by your employees. One thing i have proof of is the email when she confirmed rental and parking will stay at a special rate of R3500 and R350 for 12 months of contract, when i went to your office in June to pay for parking leasing fee and rental for July, i am now being amazed that there was no VAT charged on the R350 for parking, asked Zandile why she didn't explain so that i can expect to pay more, she tells she don't work for parking dept so she wouldn't know, but i have an email with her when she confirmed it'll stay at R350, the same person who now say she wouldn't know because she works with rental not parking. Okay i forgave her because the difference was only from R350 to R402. Now i am disgusted by the fact that my rental invoice now come with an additional amount of parking and Stella tells me i didn't pay deposit for parking, I'm telling her that Zandile confirmed to me no deposit, again she says she wouldn't confirm for parking since she doesn't work in parking department and i was a telephone conversation when i needed clarity, now i can't prove that it was an understanding i got from her. She seem to be getting away with everything and i am fed up. Someone needs to accounts, i really cannot deal with this incompetence, I've stayed at Vuselela and the consultant what helped me never mislead me only to run away from accountability, but now staying at Splendid with the consultant Zandile really feels like a curse. Someone needs to account, i can't deal with those ladies anymore.
