Poor administration and refusal to assist in paid for function

Duja Consulting are responsible for facilitating the accounts of my upmarket estate in North West Province. A recent request for a simple change to address details on the control portal app was met with refusal and in fact I was replied to with a reprimand from the staff of the business. On requesting the staff to provide the relevant owners (of Duja) details for the matter to be escalated, they refused. In fact, they did the complete opposite to what was asked of them and in so doing acted against their own advice.

Further to this, they regularly send out incorrect statements (nil balances) and also send other residents bills to myself and hence I expect mine to other residents, a contravention of PoPI.
