is this a real collection agency.  they said they represent quick cash. and I made payment through my account.  should I be scared and shut my account down,. or are they a legitimate business?

Its a collection agency called NRS

These people continaully call me and harrass me at home and work.  I have asked for proof of this bill and they will not send me anything.  They are awful people.

I'm tired of getting calls from this number. Different "agents" are calling me telling me that there is an investigation going on with my name and SSN something about a check fraud. WElp, I don't write any checks at all! And she kept asking me to verify my last numbers of my SSN. I told her no and she got mad and said well then I have no choice to push this through. Ok, go for it there toots! Push something through that was never there to be in the first place! This is a scam I believe to collect money that you don't owe! These people need to be caught and in jail!!!
