Repetitive unsolicited calls

They call several times a day from different area codes, cities, states, extensions.  Always the same company. I've told them to remove me from their call list numerous times. I am also on the national do not call registry.  They are evasive when asked who they are and will sometimes hang up. They always say "card memeber services".   This is the last number they called from:  +1 (347) 985-4951 New York, NY
