It seems that more and more lately, that Accounts Receivable Technology is becoming more and more aggresvive. They are no where near as bad as ECA, but I would advice anyone who is dealing with a collection agency to dial from a number not affiliated to you whatsoever. Dial from a payphone if you have.
I did a little investigative work from my work phone the other day for a member, and the swtichboard operator got really offensive. I simply stated that believed I had the wrong number and asked for "Dave Sumptner". He came back after about 2 seconds of seach and asked for my info. I simply told him, what is the name of your company and I can tell you if it was for me, or maybe one of my other 6 roommates. He traced the call and got bilegerant, and said he'd be contacting my employer.
collection agencies are getting more defiant, when it comes to the FCA laws.
Whenever dealing with any bill collector, it would be in your best interest if you had a recorder. I know it's not always affordable to some, but it could protect you in the future.
Just my opinion....
