You just have to call them back. It's a number belonging to Everest College. When you call them back, they will (automated) ask you if you would not like to recieve future calls, to enter in your phone number and press pound.
Called this number and someone answered in a minute or so. I told them to remove my number and they said they would. I also told them that they had an enormous PR problem and told them to search their phone numbers on line. I told them that hundreds and hundreds of people were trashing their college online. We'll see if they do anything about this.
I started receiving calls from this phone number ever since I requested information from the Everest Institute website, I also looked up some other college websites. I thought the calls were coming from some telemarketer because someone at Everest actually called me from a local number and sent me a text as well. The calls started on a Sunday, of all days, and have continued every day of the week about 10 times a day. The latest call I received was at 8:30PM which I find very strange for a "college" to be calling at this hour. Like everyone else, I didn't answer any of the phone calls and they never left any messages either. Thank goodness I'm not the only one who has had this problem so I have done what others have suggested and called them back and someone answered nice as can be and said they were from Everest. I requested to be taken off their list and they asked for my number and said my number has been entered to not receive any more calls. We'll see if this really happens.
