Unwanted phone calls

This company keeps calling me; even though I told them to take my number off their call list.  It starts as a recording stating they can lower my interest rate on my credit cards.  Then recording says press the #1 key to speak to a rep.  I once even told them to take my number off their call list; but they keep calling.  They even call from a number with my local area code.  Their latest number is 228-343-8048.  This harassment needs to stop!
