Inconsistency in payments

This needs negative stars...

I am utterly disappointed by the service rendered by the NRE in Bloemfontein, such a big agency with so much respect but their response to clients is non-existent. I have so many complaints about them, including their failure to inform municipality about my contact details until my account was handed over to the lawyers to them giving my number to other agencies asking if I'm selling my property, but I'll stick to this one for now.

I have not received a payment from them for last month's rent so I thought something might be an issue and they might have overlooked to inform me about it. Then I sent an email to enquire on 05/03/2020 and it was forwarded to the person responsible, no response. I sent another one on 09/03/2020 to the responsible person, no response. Called today to enquire and was told she is out of the office will get back to me, it's almost the end of business day and still nothing. This is frustrating as it has a negative impact on my finances and I have raised this to them a number of time via email, they never explain anything. This ranges from part payments, late payments, non payments and emails are never responded to, they just pay whatever inconsistent amount they want to keep you shut. Surprisingly enough, I have never been in areas with my account. So I am wondering if this is standard practice across the agency or is it something against me an an individual?

I'll be surprised if I ever get a response for this, because really honestly they care more about money than the clients giving them money.
