Just about every day, ofter 2-3 times a day. Never anyone on the other end. I am registered on pennsylvania's do not call list and have been since its inception.

Periodically, I get calls from this number.  No messages are left.  Phone lists

I have been on the do not call registry for several years now.  By getting on the registry you can file a complaint against this company.  Everytime they call you its supposed to be a $500 fine.  Since I have started filing complains EVERY TIME this number called me it has gone from being called every day 7 days a week to, once every 2 weeks.  It only takes a few minutes so start filing those complaints, maybe Qwest Corporation out of Maricopa county in Phoenix, AZ will get the hint.
enclosed is a link to getting on the do not call registry as well as where to file the complaints.

Every day for the last 3 weeks, someone from this number keeps calling our home phone number in Utah, but when we answer, there is nobody on the other end, and it just hangs up.  I've tried to find out who this number belongs to; so glad I found out who this is.  Will be filing a complaint with the FCC.

calls every day for the last 3 month, just hanging up.  I don't need this annoyance.

receive call often but just silence on other end

623-934-4736 has been calling repeatedly with no one answering when we answer.  I will see if I can find a formal way to complain.  If I find out that they are affiliated with any magazine I subscribe to, I will file a complaint with them.

"Preferred Reader" calls us at least twice a day, even after we've asked them to stop.  This morning when I asked them to stop, the woman got snotty and hung up on me.  How do we get this to stop?!!!

"Preferred Reader" keeps calling during the day and evening. Have asked them to remove our number. The magazine they are trying to get us to renew is Popular Mechanics. Haven't had that magazine in years!
