INCORRECT BILLING & LACK OF FEEDBACK

I am a tenant at Pennyville housing in Johannesburg Soweto , that was owned by Zelri properties on 29/09 I got a letter and a statement saying that Renico Group are the new owners , On my September statement it said that I had to pay R 3025 rent which is fine ,but there was another amount of R 800.00 which I know nothing of, This is apparently the balance from the previous owners (Zelri prop) which I know nothing about.<br> On my last September statement from Zelri there was a total of R 3550 that reflected ,I paid that money . When I queried the new statement from Renico with Michelle Taylor she told me this was the balance she received from Zelri Prop,I even sent her the proof of payment ,but all was in vain as she was not even bothered to assist. When I contact Zelri properties , I get told I need to query this with the new owners (Renico ) as they are no longer involved in Pennyville housing .Now a month later (23/10) I get an Oct statement reflecting that I owe R 300 ,from the R 800 I supposedly owed from September. As far as I know rent is R 3025,and the balances I owed from the previous owners statement I settled , I cannot understand why suddenly there's money outstanding ?
