Incorrect Rental rate app****

I have taken up rental for the last 7 months with Woodford via the King Shaka branch. My experience at this branch is inconstant as the recon of my account has been messed up whereby my holding deposit keeps diminishing due to the incorrect rental rate which is calculated incorrectly each time i make a reservation. The rental agreement does not match the rates on my confirmed booking / reservation. I have escalated this matter and keep getting promises that it will be fixed but when i go back to collect my next booking, it's the same. This is really becoming frustrating and a waste of my time when collecting my rental at King Shaka. @Dinesh, Smangele, Zufer and Jay please can you ensure that my account is rectified and i do not have this issue on my next rental.
