I have XXXX complaints : faulty billing practices and abusive practices experienced by employees of National Credit Systems. My account was forwarded to NCS in XXXX XXXX I assume ) after moving from XXXX at XXXX XXXX and having a balance due of {$210.00}. I did not receive the bill at my new address until well after the deadline to pay before being forwarded to a collection agency. 

I received the NCS 's contact information from XXXX at XXXX and called NCS XXXX to attempt to resolve. I have had XXXX interactions with NCS all have been a disaster. Represenatives are extremely rude, talking over me, and hostile - the manager hung up on me ( his name was XXXX XXXX XXXX although I was simply trying to report my interactions with XXXX earlier representatives and provide proof of payment. 

The second complaint involves their billing practices. I authorized an electronic check on XXXX/XXXX/2015, the funds were deducted by NCS on XXXX/XXXX/2015 yet I have not been given credit for the payment, I continue to receive collection calls, and have reengaged XXXX at XXXX XXXX, because I can get nowhere with these people. 

Last, they leave detailed threatening messages on my cell phone and voicemail such as " this is an attempt to collect a debt ... we may engage law enforcement ... ''. This is inappropriate and I doubt legal. 

The point of this complaint is to get assistance with getting credit for a payment made and to report their abuse practices.
