If you have a cell phone, simply install a firewall of sorts to block that number, I have Blacklist and it works just fine!, if you have a residential landline telephone you may want to contact and report to your local telephone company about the harassing calls! Remember, in the U.S. if someone is calling your phone, it can be checked and you can find the identity of the caller/company.
I have been getting this call and from other numbers as well. I just got this cell phone and I think it may have something to do with it being a prepaid phone. I never got these calls while I had a contract phone. They call all times of the day and night and never leave messages. Also, the ones that I do manage to get to in time, they have an automated recording saying "please hold for a representative"... When they finally do come on the line, they are usually very rude to me. Come on people! I have no clue who you are! Quit harassing me!
