they keep calling, almost 20 times a day, i ask to speak with the supervisor and they hung up on me. Is there anything I can do to make them stop calling

I have been on call lately for work.  With only 2-4 hours of snatched sleep time and this.... machine kept calling me every 10-20 minutes with this automated message.  It is a disgusting "organization".  I am horrified that our "consumer protection" regulations allow this harassment.  I contacted my cell phone service provider and they said that they were unable to block it.  They listened to the 20 minute automated speal and then they could tell the "automated" company to cease calling.  WHY am I BLACKMAILED into spending my cell minutes and being FORCED to listen to their speal so I can get some sleep and still have my phone on to do my job.  This has got to be illegal.  It is absolutely driving me crazy.  Anyone know of an attorney handling this?

It's best if you do have a cell, to set a profile for the person, name it whatever you like.  :)  Then, assign a special ring, the ring you assign to the number is MUTE.  This way your phone will not ring, Viola, no more calls.  OK?  You will see the calls in your call log registry, but that's all.  Send them a cease and desist Text as well.  If the text goes through, this is a cell phone.  If not it's a landline.  
I've texted a few, and they went through and I verified online they were not landlines but Cell's.

This will at least give you some relief.  It really works well, if it's your landline, then I suggest you set up an online number and put them on rotary and call them all day long on redial as someone else suggested.

Also you can GOOGLE EARTH onto that exact local.  Interesting.  :)

I just wanted to pass on though, assign this caller in your profile as a contact and give them that special ring.  Maybe one that says [***] Calling Again, or whatever flips your trigger.  Do NOT give them any personal information whatsoever.  Mute your lovely HDTV soundbar at 100% loud and as soon as you have them on the line, unmute it as you hold the phone to the speaker.  (ouch)

I hope some of these options work for you.  Doesn't look like they are making much money from home, does it....hehe.  So sorry so many of you are being so upset, I do understand but there are measures to take.  Remain calm, and there are ways to strike back.
