Who called from 3475300772

I've received several text messages from them.  When I called to tell them to remove me from their list and that i do not want their services, they hung up on me.

Have received several text messages from this number.  Is there anyway to stop them?

I've gotten two text messages from them today. The first one was about visiting their website giving me a $200 voucher and the second asked if I wanted a free laptop.

I have gotten about four text messages and have replied to be removed but I haven't been.  Calling them resulted in a hang up.

I just tried calling the number to be removed.  I got voicemail, which was full.
