507-708-5312

Called me, twice and no message either time.

Called twice now and no message was left.

Called and did not leave a message. Caller ID listed number and NAME UNAVAILABL.

This number showed up on our landline phone.  I didn't answer since no name was associated with the number.  No message was left.

I just read on another site this is a scam regarding the federal reserve. This is the message they were sent. "Hello, this call is from law enforcement the federal Reserve system. We have found suspicious activity from your banking account Peter, which there is a legal case being filed under your name in there is an arrest warrant issued for the statement in order to talk through an officer from law enforcement is a federal reserve first one being hold the line."

My caller ID listed it as a charity call.  But my spam blocker told me to not answer the phone. I waited for it to go to voice mail.  No message was left.  This is the second or third time I've had a call from that number.

Call back gets, "Hello you have reached MDS Communications."  Goes on to explain that they are telephone fundraising company that specializes in raising money for non profit organizations.  Also explains that they are exempt from the DNC list but gives you the option to be added to their internal DNC list.  Of course numbers can be spoofed so be careful when giving information over the phone.
