Recieved 4 calls today.  Called back and could not speak with anyone or leave a message.

Yes, I got 25 times yesterday alone.  I answered once and an agent asked me someone else so I told her that she had wrong number.  Then she started saying "Oh, I'm so sorry but since I got you on a phone ......." then I hung up.  They started calling from 9am ET to 9pm last night. I had enough and called the number, the operate gave you 2 options, 1 is to speak to the Customer service, and 2 to be on 'their do not call list' so I choose an option 2 but Guess WHAT, they still called 9:19am ET again today!!!!

Who is it that's calling and for what?

I am not sure.  When I called back this number, they don't state their business.  Then when I chose option 1 for customer service, their respond was 'high call volume and no one can take a call, call back again in the different time."

Recieved 2 calls today and 1 yesterday.  No messages.
