I received a call from this company. They are Credit Card Services. If you listen to their "Pitch" and decline it, they will swear at you. It sounds like their head is going to explode they get so PO'd I have since blocked this number and (321) 304-9999.
PS - I am on the National and State DNC lists and it doesn't make any difference to these people.
Contact your telco or if you have cable contact them. They all provide call blocking for numbers. You will need to do this often as they change numbers.Their caller ID usually starts with a "V" then a series of numbers.
