****** idiots who don't know how to communicate!

These idiots are honestly the worst, they keep sending me messages that I owe them money from a Property Services place that I moved into in July. The actual place says that I owe them nothing and even after emailing and calling several times I have received no information regarding what I owe and when I owe it from and when it was transferred to them. All they do is keep adding interest to my bill. Its honestly irritating, they don't even have the decency to respond to any communication at all!
