I also receive about two calls a day from this company.  They use 800-566-1703 and 866-347-9977.  I have never had their service but the Verizon phone number I have must be registered with them for some reason.  I have reported both numbers to THE DO NOT CALL CENTER managed by the FCC, but it has done no good.

This is from the www.donotcal.gov  from the file a complaint section 1.You may file a complaint if you received an unwanted call after your number was on the National Registry for 31 days
2.You may also file a complaint if you received a call that used a recorded message instead of a live person (whether or not your number was on the Registry).
*Reminder:Even if your number is registered, charities, political organizations, and telephone surveyors may continue to call you. Companies with which you do business may also continue to call, unless you have asked them to stop calling you. If you have asked them to stop calling, please keep a record of the date you made the request and include that information in the comment section of any complaint you submit against that company. Click Here for more information about the companies that may continue to call the numbers on the Registry.
Debt collectors may also continue to call you whether your number is on the Registry or not. If you have a complaint about a debt collector, please Click Here to file your complaint. For more information about your rights regarding debt collectors Click Here.

It is Clear Wire. Block their number and all of the others they use.

The auto caller is an infringement on our privacy - - - they call day and night. A written correspondence finally arrived and I wrote them a letter with a final payment. Return phone calls to any of their 800 family of numbers (they have a lot of them so beware) resulted in a transfer to a number of foreign countries. None in the US. Report them to consumer advocacy groups and write to them. Not answering calls does not halt their practice. FCC needs to be told. Blco the number.

I looked up the FCC site - check this out too. http://www.fcc.gov/guides/unwanted-telephone-marketing-calls

There is strength in numbers so you do your part and I'll do mine. We can't let them keep this up.

I need a way to get these harrassers off my back. The auto caller is an infringement on my privacy - - - they call day and night. I cannot even find a place to return my equipment in driving distance. I am SO DONE with these jokers!  A written correspondence finally arrived and I wrote them a letter.

I cancelled my service 2 months ago.  They call me night and day harrassing me to purchase from them again.  It's awful.  I don't answer the phone any longer.  I don't advise anyone doing business with them!

They are terrible. Please no one ever try their internet service, you will be sorry. Go to their own customer website and read the postings in their forums and you will see what I mean. They are a scam company.

it's clear/clearwire call me four or five times a day. the internet service there is the worst.

They keep calling me at least 4 times a day, some times in the early morning, it gets old. I wish I had never gotten clear's internet, it is so terrible, and now they harass you when you quit

This is a number from Clear - trying to get you to re-connect service after you have had it terminated.  They spend a ton of time and money trying to get you back - when they should just spend the money to make their service better.  I receive 2 to 4 calls a day sometimes.  I DO NOT recommend anyone use Clear for internet service.

Need to find out who it is.

It is from Clear Communications

It's from Clear, they've been calling multiple times a day and leaving automated voice messages saying they have a new deal for me... dumb. don't answer.

Its Clearwire

Received two calls from this number (5/30/11 & 5/31/11), but no message left.  Curious who it is.
