Enterprise Recovery Systems? Hrrm, a real piece of work, that bunch. Reportedly they purchase the junkiest of junk debt and employ ignorant and hostile reps to wring their fear funds through desperate and illegal tactics. Nothing much uncommon among the Buffalo Bullies, but they should be approached with caution. Learn your rights as an alleged debtor under the FDCPA at FTC-dot-gov.

First this number sent a text to my boyfriend's cell phone saying "Got to get up early tomorrow for church," and then they called the phone and left the following message: "Hello, this is Mr. Smith with the ERS calling for Mr. Boyfriend's Surnames about a discrepancy in your 2009 taxes. If you call me back as soon as possible I would appreciate it." This message was sent at midnight!

I looked up the ERS and from what I found it is a shady collection agency that is supposed to collect on student loans. I'm not going to bother calling back because it sounds incredibly suspicious.
