Thye keep calling and calling it must be a scam.  They do not seem to know much about me.

This caller is claiming to lower credit card interest rate. The name appearingcaller id is Durelle Rene.

I recieved a call from this number as well.  They claimed it was my last chance to lower my interest rate.  They put me on hold and never came back.  I tried to return the call and got a disconnected number.  They stated they represented Visa and Mastercard.

Someone with this number calls and doesn't leave a message. Shows "out of area" and "(506) 228-4563".

Many of these callers use fake caller I.D.s, so next time I might engage one of these sleazes to see how much information I can get.  Probably not much--they're professionals and could be operating out of Belarus for all I know.
