Calls constantly and disconnects when the call is answered. My CID says MDSS. I googled for this company name and it looks like it's Marketing Decision Support Systems, Inc. They do marketing surveys. I am blocking this number.

Calls constantly and no one is there when you pick up.  480-967-0402  I want it blocked

Rec'd call from this number, the party asked for my husband by his 'correct first name'.  I asked who was calling twice & the other party (a male voice) just hung up on me.  I tried to call the number back and just got an endless ringing phone!

I have received calls in the past from this number but there was never anyone on the other end, this is the first time someone actually spoke.  I would like to have this number blocked but do not know how to do that on my phone!  Any suggestions?

Calls at least three times a night.  no one ever on the line.  I am sick of this crap.
