Been getting calls around the clock from this number that just hang up when I answer. Tonight they left a message for me to call back on 800#. Said to call Crystal at ARS National at 1-866-725-4895-ext 3141about some important papers she had laying on her desk that I may not know about. No answer when I called back, so I came to internet to search and see what I could find out. It's a collection agency that uses all kinds of tricks, threats, etc. to get you to pay on bills you may or may not owe and they make it very hard for you to get the information you need to know if the collection is legitimate,...this is according to numerous sites I've read tonight.
