called me at XXXX XXXX on XXXX/XXXX/XX/XX/2015 saying that I owe {$1600.00} and I talked to the management company that filed it against me and they told me adjusted it to {$940.00}. XXXX calls me saying I have to make a payment before XXXX on XXXX/XXXX/XX/XX/2015 after the fact that I asked them to mail me something stating that balance and they refused to.
