Keep getting calls from this number, no one answers.  It happens almost everyday.  How do we stop this

I have gotten calls from Miller Plante with various numbers, 321-460-1502, 321-460-1555. At first I thought I remembered it as Robert Plant, which was strange, and then I thought it was just someone lost, because I have never answered it. I tried the 800 number above this but only got a recording to leave a message. I've started turning my ringer off and only leaving it on a couple hours of the day when I am up and home, it's taken care of a lot of nuisance calls, but not all.

An hour after we got our phone installed, our phone rang and the caller ID was showing Miller Plante.  When we answered, they would hang up.  They have called at least 3-4 times a day.  The number for Miller Plante keeps changing everytime they call.  When I call them back, I get a recording stating the number has been disconnected.  The numbers of Miller Plante that I've received are: 321-460-1502 and 407-875-3450.  After looking up information on them, I came across a 1-800-929-2722 number to call them back and get on their "do not call" list.  The representative said it would take up to thirty days to get our number taken off.  Good luck!

I have been getting calls from them too.  I just got a call from "Miller Plante" from 321-460-1502 a few minutes ago.  I don't know who they are and they won't tell me when I ask.  The gentleman asked for my husband, and I told him my husband is at work right now (come on...it's the middle of the morning).  I tried to tell him I was his wife and asked if I could help him, but he talked over me stating he would just try him back later.  He won't state who he is with or why he is calling, and I can't find any information on this company nor do I even know what they want because the gentleman won't tell me.  I just tried to call them back and I only get a busy signal.

I just called the 1-800-929-2722 number from an earlier post and told them I was getting these calls from Miller Plante and they asked for my phone number and said when she typed it in nothing came up. I told her they have been calling for days and asked her what company it was and she asked if I was a homeowner with a septic system. When I told her I rented she said I'm sorry that was what it was about septic systems.
