Customer Service Afcho

I Am A Three Month Tenant at The Falls 2 And I Haven't Received My Invoices From The First Month. I have tried calling in to the office to check if my email address is correct and it was. I even tried changing it to my work address but still haven't received it. I called in several times requesting for a invoice and for my email address to be changed however I was just told that someone will give me a call back I then paid the amount that I paid the previous month and I received a credit record alert message from AFCHO stating that only part of my May rent was paid I then called back immediately and still no help was provided. Their customer service is ridiculous and they have not been the easiest people to deal with. Every month I have to fight with with afcho to send my invoice/statement and then they have the decency to send me an SMS about a credit record alert. This is RIDICULOUS
