Oneway feedback

I received a call for debt that I did not know existed as the Emfuleni Municipality never send me bills for this property since I contacted them to make the two properties I own into one. I visited the Vanderbijlpark branch of MBD to explain my situation and the agent insisted that I make an arrangement to pay the debt though I tried to explain that there is a mistake on the side of the municipality and ultimately decided to sort this out with the municipality direct. I informed MBD about the bad treatment through their website but they responded with the requirement of their ref or my ID number. I send them my ID number but they never responded. I was able to correct the municipal error and made arrangements to pay the reduced debt to the municipality and informed MBD about this arrangement at their Vanderbijlpark branch and through an email. At least two people at MBD read my email and none has bothered to respond. The only correspondence I recieve from them are twice weekly sms that demand that I pay Emfuleni sothat I \avoid disconnection of services"and that immediate payment is required to \""avoid further action\"". Why does MBD never listen and communicate oneway?"""
