Huurkor - Poor administration and no response

We've moved into our estate in September 2022, having signed a debit order against our savings account for monthly levies. Whilst expensively renovating the house, the savings account were used to pay for the renovations,effectively making this a secondary account. The debit orders did not clear, however our monthly statements from Huurkor reflected a R0 balance due. Not 1 did Huurkor communicate the same to us.Fast forward numerous months, Huurkor wrote back the full amount and expected this to be paid immediately. We informed them that we would pay double levies each month,bringing the levies up to date in 6 months.Currently they are levying penalties on a monthly basis,almost amounting to the monthly levy, rendering us unable to catch up on the levies. The penalties are not based on a % of the outstanding amount, but in some cases R300 a month,which exceeds 10% of the total amount due. They do not respond to emails,neither do they (Sarie) respond to phone calls.
